  • Removal of Anionic Dye Congo Red from Aqueous Environment Using
    www.nature.com/scientificreports OPEN Removal of anionic dye Congo red from aqueous environment using polyvinyl alcohol/sodium alginate/ ZSM‑5 zeolite membrane Sabarish Radoor1*, Jasila Karayil2, Jyotishkumar Parameswaranpillai1 & Suchart Siengchin1* In this study, a novel PVA/SA/ZSM‑5 zeolite membrane with good regeneration capacity was successfully prepared by solvent casting technique. The properties of the membranes were assessed by employing diferent characterization techniques such as X‑ray difraction (XRD), Fourier‑transform infrared spectroscopy (FT‑IR), scanning electron microscope (SEM), optical microscopy (OP), thermogravimetric analysis (TGA), contact angle and universal testing machine (UTM). XRD, TGA and UTM results revealed that the crystallinity and thermo‑mechanical performance of the membrane could be tuned with zeolite content. The successful incorporation of zeolite into the polymer matrix was confrmed by FT‑IR, SEM and OP analysis. The adsorption ability of the as‑prepared membrane was evaluated with a model anionic dye, Congo red. Adsorption studies show that the removal efciency of the membrane could be tuned by varying zeolite content, initial concentration of dye, contact time, pH and temperature. Maximum dye adsorption (5.33 mg/g) was observed for 2.5 wt% zeolite loaded membrane, at an initial dye concentration of 10 ppm, pH 3 and temperature 30 °C. The antibacterial efciency of the membrane against gram‑positive (Staphylococcus aureus) and gram‑negative bacteria (Escherichia coli) was also reported. The results show that membrane inhibits the growth of both gram‑positive and gram‑negative bacteria. The adsorption isotherm was studied using two models: Langmuir and Freundlich isotherm. The results show that the experimental data ftted well with Freundlich isotherm with a high correlation coefcient (R2 = 0.998).

  • Crosslinked Poly(Vinyl Alcohol) Membranes
    International Journal of ChemTech Research CODEN (USA): IJCRGG, ISSN: 0974-4290, ISSN(Online):2455-9555 Vol.10 No.3, pp 118-127, 2017 Synthesis and Physical-Chemical Characterization of DEA- Crosslinked Poly(Vinyl Alcohol) Membranes María T. Acevedo1*, Alejandra Tapia1, Álvaro Realpe1 1Department of Chemical Engineering, Research Group of Modeling of Particles and Processes, Engineering Faculty, Universidad de Cartagena, Colombia Abstract : In this research, crosslinked PVA was impregnated with 0, 15 and 20% of diethanolamine so as to study the effect of the alkanolamine on the physical-chemical properties which are connected to the CO2 separating process via membranes. Formaldehyde and a porous membrane of polisulfone were used as crosslinking agent and support, respectively. Membranes were characterized by FTIR, SEM-EDS, contact angle, water absorption and porosity measurements. The results suggest that although the water absorption in the bulk of polymer diminished when the percentage of diethnaolamine increased, the surface hydrophilicity and appearance of the membranes were not appreciably affected due to this modification. A favorable balance of properties such as water uptake, the porosity and the superficial hidrophilicity were achieved using the crosslinking and synthesis conditions proposed in this paper, considering the positive effect of those characteristics in the permeability/selectivity of CO2 through the membrane. Keyword : crosslinked PVA, diethanolamine, CO2 separating process, membranes, surface hydrophilicity. Introduction Pollution associated with emissions of carbon dioxide (CO2) is one of the preeminent environmental issues [1,2]. The high level of CO2 emission levels is arising from combustion of fossil fuel, accelerated increase in the energy consumption, population and industries, including cement and metal production, which have caused different kinds of devastating effects in particular the increase in global temperature with severe consequences on ecosystems, biodiversity and sea levels [3].

    Polymer Journal, Vol. 36, No. 6, pp. 472—477 (2004) Crosslinking of Poly(vinyl alcohol) via Bis( -hydroxyethyl) Sulfone y Kazuhiro KUMETA,Ã;ÃÃ Ichiro NAGASHIMA,ÃÃ Shigetoshi MATSUI,Ã and Kensaku MIZOGUCHIÃ; ÃDepartment of Materials Science and Chemical Engineering, Shizuoka University, 3-5-1 Johoku, Hamamatsu 432-8561, Japan ÃÃNitivy Co., 300 Zenzaemon, Fujieda 426-0053, Japan (Received November 4, 2003; Accepted March 29, 2004; Published June 15, 2004) ABSTRACT: Poly(vinyl alcohol) (PVA) was crosslinked via bis( -hydroxyethyl) sulfone (BHES) at elevated tem- peratures to improve the water resistance. The best conditions for the crosslinking such as temperature, heat-treatment period, and amount of BHES or catalyst were screened out. Water resistance of the crosslinked PVA was characterized in terms of swelling and weight loss in water. The addition of BHES into PVA followed by heating at elevated temper- ature resulted in successful formation of crosslinking structure. The crosslinking occurs above 160 C and takes shorter period at high temperature than low temperature. The crosslinking catalyst, sodium carbonate, acts more effectively at 160 C than at 200 C. The results from thermal analysis using a differential scanning calorimetry revealed that the cat- alyst functions against BHES to lower the temperature for the crosslinking reaction and that even the crosslinked films have the PVA crystalline. The crosslinking procedure using BHES and sodium carbonate is applicable to form ion-ex- change fibers based on PVA with high water resistance.

Current uses of polyvinyl alcohol can be found in Table 1. The FDA’s VCRP database indicates that uses have increased from 37 to 225. The majority of the uses are in leave-on products such as eye makeup and skin care products. In 1998, the industry reported the maximum use concentration to be < 25%, with 13% reported for a hydrolyzed version of the ingredient in paste masks (mud packs). Presently, the industry reported a maximum use concentration range of 0.0035% to 15%, with 15% reported in “other” skin care preparation products.
