Abramson1, C. Meiller1, P. Beaunier2, V. Dupuis1, L. Perrigaud1, A. Bée1 and V. Cabuil1 1Laboratoire de Physicochimie des Electrolytes, Colloïdes et Sciences Analytiques - (PECSA-UMR 7195 UPMC-CNRS-ESPCI) UPMC – 4, place Jussieu - 75 252 Paris cedex 5 – France 2Laboratoire de Réactivité de Surface (LRS-UMR 7197 UPMC-CNRS) UPMC – 4, place Jussieu - 75 252 Paris cedex 5 - France The use of magnetic materials as adsorbents or heterogeneous catalysts in wastewater treatment is an innovative technology that is increasingly studied. [1] Indeed these materials may be easily recovered by the simple application of an external magnetic field given by a magnet or an electromagnet. This separation technique may be more interesting than conventional recovery methods such as filtration or decantation, particularly when the effluents contain particles in suspension. Here we describe the preparation of magnetic nanocomposite beads for water remediation using green-oriented methods. We have thus prepared millimeter-sized magnetic silica beads using alginate as a green biopolymer template. Biopolymers produced from renewable resources are increasingly used in the synthesis of nanocomposite materials since they comply with the requirements of green chemistry and induce an original organization of the material, frequently at a multiscale level [2]. The beads were synthesized in three steps. First, magnetic nanoparticles were encapsulated in alginate beads. Secondly, an inorganic network was polymerised into the beads by a sol-gel method. Finally, the alginate template was eliminated by a mild method (see scheme). We have studied the porosity, morphology and magnetic properties of the beads using several characterisation methods. Finally, since these highly porous materials could be used as magnetic adsorbents in water remediation, we have tested their sorptive properties in aqueous solution. Alginate Inorganic network network + Magnetic nanoparticles We also present our first attempts to synthesize micrometer-sized magnetic silica beads by sol-gel method in water-in-oil emulsion. During this process, it is possible to use vegetable oil and natural surfactants. Since these materials may be modified by a TiO2 shell they could be used as highly efficient magnetic photocatalysts for the removal of organic pollutants from water. References [1] Q. Jiuhui, J.

This presentation describes a methodology to screen for pharmaceuticals and their metabolites in sewage water using Ultra-Performance Liquid Chromatography in combination with Quadrupole-Time-of-Flight Mass Spectrometry (UPLC/QTOF-MS). Reference mass spectra of metabolites were obtained from the analysis of urine samples originating from consumers of the pharmaceuticals in question. Municipal sewage waters treated by different technologies e.g. activated sludge, a membrane bio-reactor, biofiltration, activated carbon, ozonization, and UV-light in combination with hydrogen peroxide, were investigated. Metabolites of common pharmaceuticals such as ibuprofen, carbamazepine, diclofenac, and metoprolol were among the most abundant.

Or 3 Multivariate characterisation of industrial chemicals and strategies to identify potential environmental pollutants Patrik Andersson, Stefan Rännar, Mia Stenberg, Mats Tysklind Chemistry Department, Umeå university, Sweden In this study chemical descriptors were calculated for chemicals of the European inventory of existing commercial chemical substances (EINECS) and those categorized as low and high volume production chemicals. A multivariate characterization of the EINECS chemicals using principal component analysis (PCA) and 68 chemical descriptors resulted in five principal components, mainly reflecting size, lipophilicity, flexibility, number of halogens, and electronic properties. These five PCs form the basis of the map of organic, industrial chemicals. The similarities and diversity in chemical characteristics of the substances in relation to their persistence (P), bioaccumulation (B) and long-range transport potential were then examined, by superimposing five sets of entries obtained from other relevant databases onto the map. These sets displayed very similar diversity patterns in the map, although with a spread in all five PC vectors. However, substances listed by the United Nations Environment Program as persistent organic pollutants (UNEP POPs) were clearly grouped with respect to each of the five PCs. Furthermore, different means to cluster the data is presented to identify potential environmental pollutants using multivariate techniques combined with various statistical designs and cluster based techniques. These tools can be used to illustrate similarities and differences in chemical properties, and to be able to make predictions of, and investigate new chemicals. The results of this presentation demonstrate that non-testing methods such as read-across, based on molecular similarities, can reduce the requirements to test industrial chemicals, provided that they are applied carefully, in combination with sound chemical knowledge. Or 4 The aerosolized biosphere - Recent insights into the chemical nature of biogenic aerosols Meinrat O. Andreae Max Planck Institute for Chemistry, Mainz, Germany The biosphere is a major source of atmospheric aerosol particles. Figuratively speaking, there are different ways for parts of the biosphere to become airborne: 1) “deliberately”, 2) “accidentally”, and 3) “by force”. By “deliberately” I am referring to the fact that the biosphere releases gaseous aerosol precursors and primary biogenic aerosol particles (PBAP; e.g., spores) in an apparently controlled and purposeful manner. The production of secondary organic aerosol can in some ways also be thought of as the consequence of a “deliberate” release of terpenoids and other VOCs. Other types of PBAP are released more “accidentally”, when material such as leaf waxes, plant fragments and bacteria, are suspended from the ground or vegetation by atmospheric turbulence. Finally, a large part of the biosphere forcibly becomes airborne when vegetation is burned by humans action or wildfires. In my presentation, I will compare and contrast the optical, chemical and cloud nucleating properties of secondary organic, primary biogenic, and biomass-burning aerosols, emphasizing recent observations. Or 5 Enzymes as catalysts: Opportunities for green and selective oxidations Isabel W.C.E. Arends Biocatalysis and Organic Chemistry, Department of Biotechnology, Delft University of Technology. Julianalaan 136 2628 BL Delft, The Netherlands. [email protected] Nature uses enzymes to catalyze a wealth of biotransformations. However in practice these transformations are carried out in-vivo under conditions which are far from suitable for large scale production of chemicals. It is our challenge to engineer or design enzymes in such a way that they can be employed in-vitro as catalysts. Especially for oxidations, the power of enzymes can circumvent the use of halogen-containing and environmentally demanding oxidants, by using oxygen or hydrogen peroxide as clean and selective oxidants [1]. In the lecture it will be discussed how different classes of enzymes can be employed as catalysts for biocatalytic oxidations. Both oxygen transfer - insertion of an oxygen inside the molecule - with peroxidases as well as oxidative dehydrogenation using laccases will be treated. Chloroperoxidase Laccase from Caldariomyces fumago from Trametes versicolor A peroxidase has all the characteristics of a promising biocatalyst: It is a cofactor-independent biocatalyst that uses hydrogen peroxide as the oxidant and that can introduce oxygen in the substrate. The chloroperoxidase from Caldariomyces fumago is such an enzyme that can perform a variety of selective oxidations, including epoxidations [2].

To have a deep understanding of the reaction mechanisms, the structural characterizations of organocopper intermediates become indispensable. Meanwhile, the structure- function relationship of organocopper compounds would advance rational design and development of new Cu-based reactions and organocopper reagents. Compared to the mono- carbonic ligand, the C,N- and C,C-bidentate ligands better stabilize the unstable organocopper compounds. The bidentate ligands can chelate to the same copper atom via 휂2-mode, forming a mono-cupra-cyclic compounds with at least one acute C-Cu-C angle. When the bidentate ligands bind to two copper atoms via 휂1-mode at each coordinating site, the bimetallic macrocyclic compounds will form nearly linear C-Cu-C angles.

Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa) Infobox disclaimer and references Sodium hydroxide (NaOH), also known as lye, caustic soda and sodium hydrate, is a caustic metallic base. Caustic soda forms a strong alkaline solution when dissolved in a solvent such as water. It is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. Worldwide production in 1998 was around 45 million tonnes. Sodium hydroxide is the most used base in chemical laboratories. Pure sodium hydroxide is a white solid; available in pellets, flakes, granules and as a 50% saturated solution. It is deliquescent and readily absorbs carbon dioxide from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. It also dissolves in ethanol and methanol, though it exhibits lower solubility in these solvents than potassium hydroxide.

  • LESSON 11 THEME: Equilibriums in Solutions of Coordination Complexes
    LESSON 11 THEME: Equilibriums in solutions of coordination complexes. Heterogeneous equilibriums and processes. Research work: «Reception of complexes. Medicobiological value: the coordination complexes carry out various biological functions. So, for vital activity of a human organism the unique value has a coordination complex of iron ions with protein - haemoglobin exercising transport of oxygen from lung to tissues. In life of plants the important role is played chlorophyll - complex of magnesium, due to which the plants transmute carbone dioxide and water into composite organic matters (amylum, saccharum, etc.). The ion Cu2+is the component of several important enzymes - participants of a biological oxidizing. The coordination complexes of a cobalt considerably raise intensity of protein metabolism, regulate composition of a blood. Metalenzymes is the coordination complexes with high specificity of ions of metals, among them, except for mentioned above, is more often than others there are ions of zinc, molybden, manganese. In the whole cations almost of all metals are in alive organisms as coordination complexes. Pollution by transition metals and their compounds: mercury, lead, cadmium, chromium, nickel - can result into a poisoning. The toxicity of such compounds in many cases is explained to that these ions supersede ions of biogenic metals (Fe, Zn, Cu, W) from coordination complexes with a bioorganic ligand (for example, porphyrin). The stability of coordination complexes, formed at it, usually is higher, they collect in an organism, therefore the normal vital activity of an organism is broken and the toxicosis begins. The coordination complexes will be used in medical practice. Various metals (macroelements) introduce to the organism as coordination complexes.

Received: 7 February 2019; Accepted: 26 February 2019; Published: 2 March 2019 Abstract: Zinc is one of the essential trace elements, and plays an important role in human health. Severe zinc deficiency can negatively affect organs such as the epidermal, immune, central nervous, gastrointestinal, skeletal, and reproductive systems. In this study, we offered a novel biocompatible xanthan gum capped zinc oxide (ZnO) microstar as a potential dietary zinc supplementation for food fortification. Xanthan gum (XG) is a commercially important extracellular polysaccharide that is widely used in diverse fields such as the food, cosmetic, and pharmaceutical industries, due to its nontoxic and biocompatible properties. In this work, for the first time, we reported a green procedure for the synthesis of ZnO microstars using XG, as the stabilizing agent, without using any synthetic or toxic reagent.

    Azeez et al. Lipids in Health and Disease (2017) 16:47 DOI 10.1186/s12944-016-0405-2 RESEARCH Open Access Histomorphology, ultrastructure and fatty acid composition of the adipose tissue in pansteatitis, the potentials in understanding the underlying mechanism and diagnosis of pansteatitis in the Nile crocodile O. I. Azeez1,4*, J. G. Myburgh3, R. A. Meintjes1, M. C. Oosthuizen2 and J. P. Chamunorwa1 Abstract Background: In an effort to characterize the fat body and other adipose tissue in the Nile crocodile and the effects of pansteatitis on the structure and composition of the adipose tissue, we evaluated the regional variation in structure and fatty acid composition of healthy farmed crocodiles and those affected by pansteatitis. Methods: Adipose tissue samples were collected from the subcutaneous, visceral and intramuscular fat and the abdominal fat body of ten 4-year old juvenile crocodiles from Izinthaba Crocodile Farm, Pretoria, South Africa while pansteatitis samples were collected from visceral and intramuscular fat of crocodiles that had died of pansteatitis at the Olifant River, Mpumalanga, also in South Africa. Histomorphology, ultrastrustucture and fatty acid composition by fatty acid methyl ester (FAME) analysis were conducted. Results: Histological examination showed regional variations in the adipose tissue especially in the collagen content of the ECM, tissue perfusion and division into lobes and lobules by fibrous capsule. Considerable fibrosis, mononuclear cell infiltration especially by macrophages and lymphocytes and toxic changes in the nucleus were observed in the pansteatitis samples. Regional variation in lipid composition especially in Myristoleic (C14:1), Erucic acid (C22:1n9), and Docosadienoic acid (C22:2n6) was observed.
