  • Molybdates: an Alternative to Hexavalent Chromates in Corrosion
    Molybdates: An Alternative to Hexavalent Chromates 3ytzt7n2 in Corrosion Prevention and Control qz ,+ B3 F Stiles C. Thompson Sverdrup Technology, Inc. 626 Anchors St. NW Fort Walton Beach, FL 32548 (904) 833-7600 Introduction Hexavalent chromates have been the preferred corrosion inhibitor in military systems for years. Chromate conversion coatings are specified in MIL-STD-808, “Finishes, Materials and Processes for Corrosion Prevention and Control in Support Equipment ”, for aluminum, magnesium, and plated steel. A number of primers are formulated with zinc or strontium chromate. Passivation treatments for stainless steels frequently specify chromic acid. Some anodic coatings specify baths containing chromic and sulfuric acid and a pcst treatment or rinse with aqueous sodium dichromate. Even water-based primers formulated for volatile organic I compound (VOC) compliance in such areas as southern California contain chromate-based corrosion inhibitors. Chromates are decreasing in industrial use, however, as concerns about their environmental risks and toxicity increase. One pollution prevention approach is to substitute analogs of chromates in similar applications. Molybdate is one such analog of lower toxicity. Federal Environmental Regulations A number of environmental regulations now control hexavalent chromate. Toxic Substances Control Act (TSCA). Under TSCA, the Environmental Protection Agency @PA) must be notified 90 days prior to manufacture. EPA may restrict or prohibit manufacture where there is unreasonable risk to the environment. EPA also has the authority to require testing for health or environmental effects. No current regulation specifies molybdate. Resource Conservation and Recovery Act (RCRA). RCRA regulates the treatment, storage, transportation, and disposal of hazardous waste (HW). The EPA HW number for hexavalent chromium is D007.

A titrimetric determination of thorium Abstract A rapid, accurate method for thorium is proposed in which thorium is titrated with a standard solution of ethylenediaminetetraacetic acid (EDTA). Alizarin Red S serves as the indicator, a sharp change from pink to yellow marking the end point of the titration. The method is selective for thorium although several cations and anions interfere. A preliminary extraction of thorium nitrate by mentyl oxide provides an excellent separation of thorium from most interfering ions.

In this regard, over the President’s Message years we have channelled great efforts into the research aspects of our science. We now consider it timely to turn our Report on the 16th IUBMB attention to educational initiatives. Conference / Young To address this aim and in collaboration with FEBS, we are organising a conference on Education in Biochemistry and Molecular Biology, to be held in Scientists’ Program Rehovot (Israel) in September 2017. The conference seeks to provide a think-tank Tang Prize Foundation setting in which to draw up ideas to improve the current approach to teaching these subjects, and to generate a series of recommendations to be shared with Awardees / IUBMB Travel the educational community. In this regard, this conference will serve to propel the Fellowships changes that are required to bring education in biochemistry and molecular biology st at all levels into the 21 century. Another Way to Think About Another important aspect of education is to provide young scientists from Disease by Gregory Petsko developing countries the opportunity to attend international congresses and meetings. IUBMB is firmly committed to this endeavour and devotes significant Retrospective — financial resources to this end.

In all cases, complexes were examined by multiple spectroscopic techniques, especially HRMS (high resolution mass spectrometry), IR (infrared spectroscopy), and 1H NMR (nuclear magnetic resonance) spectroscopy. In some cases, suitable crystals for single crystal X-ray diffraction were able to be grown and the molecular structure was obtained. The molecular geometries of the products are discussed. Except for the alanine complex, all complexes incorporate water molecules into the extended lattice and exhibit N-H···O and/or O···(HOH)···O hydrogen bonding interactions. The non-covalent interactions are discussed in terms of the extended lattice structures exhibited by the structures.

The sorption isotherm results show that the adsorption process of W obeys the Freundlich model very well whereas the exchange process with Mo approximately follows the Henry model. The kinetic experiments show that the intraparticle diffusion process was the rate-determining step for W sorption on the resin, and the corresponding activation energy is calculated to be 21.976 kJ/mol.
