Poly(2-hydroxyethyl methacrylate) membranes were prepared in aqueous media with different ions and ionic strengths. The enzyme glucose oxidase was incorporated into some of these membranes. It was found that membrane water contents and ionic strengths have a linear relationship as long as the salt is not changed. When the salt was varied, only a relationship between salt concentration and water content could be observed. The membrane permeabilities were all found to be of the same order (10(-8) cm2 s-1) but the membranes were slightly more permeable to chromate ions than glucose. Incorporation of enzyme distinctly increased the water content of the membrane and permeability to both solutes.

PERMEABILITY PROPERTIES OF CHARGED HYDROGEL-CARRYING MEMBRANES AKIN, H; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (1990-02-01) Poly(2-vinylpyridine) is known to be hydrophobic, and a membrane prepared from it would not permeate water-soluble substances in aqueous media. By introducing hydrophilic poly(2-vinyl-N-methylpyridinium iodide) particles into the membrane, it would be possible to control permeation. This type of membrane was prepared and an increase in permeability was observed on increasing the amount of hydrophilic component in the membrane and decreasing the crosslink density of the hydrogel part. The size of the hydroge...
Covalent immobilization of invertase on chemically activated poly(2-hydroxyethyl methacrylate) microbeads Altinok, H.; Aksoy, S.; Tumturk, H.; Hasırcı, Nesrin (2006-10-01) Properties of invertase immobilized on poly(2-hydroxyethyl methacrylate) microbeads activated by epichlorohydrin or cyanuric chloride were studied. After 20 repeated uses for 3 days, the activity of the immobilized enzyme was 92-93%.
Investigation of phase inversion behavior of cellulose- ionic liquid solutions in relationship with membrane formation Durmaz, Elif Nur; Çulfaz Emecen, Pınar Zeynep; Department of Chemical Engineering (2017) Cellulose membranes were produced from ionic liquid solutions by phase inversion technique and thermodynamic and kinetic aspects of the process were investigated to relate these to membrane morphology and performance. In thermodynamics part, polymer-solvent, polymer-nonsolvent and polymer-solvent-nonsolvent interactions were examined experimentally, together with Hansen solubility parameter estimations. Kinetics part consisted of measuring phase inversion rate. Obtained membranes were characterized by their...
EXTRACTION OF STRONTIUM IONS WITH EMULSION LIQUID MEMBRANE TECHNIQUE Eroğlu, İnci; KALPAKCI, R; Gündüz, Güngör (1993-06-02) The aims of this study are to form a liquid membrane suitable for the extraction of strontium ions from aqueous solutions and to determine the factors influencing the stability of the membrane, the extraction efficiency and the rate of transport. The suggested membrane is composed of kerosene, Span 80 and D2EHPA. It has been observed that the extraction efficiency and the rate of transport increase with increasing ratio of emulsion to outer phase volume, stirring rate and D2EHPA concentration and decreasing...
Grafting of diallyldimethylammonium chloride on graphene oxide by RAFT polymerization for modification of nanocomposite polysulfone membranes using in water treatment Ghasemıkouchameshgı, Mahmoud; Marjani, Azam; Mahmoudian, Mehdi; Farhadi, Khalil (2017-02-01) In this study, functionalized grapheme oxide (GO) was utilized as an additive for the preparation of nanocomposite membrane. For growing the polymer chains on the graphene oxide surface, the control living radical polymerization (reversible addition fragmentation chain transfer polymerization (RAFT) technique), was applied. The RAFT agent, O-ethyl xanthate was grafted on the grapheme oxide surface and then the chains of PDADMAC grew from modified sites. GO-PDADMAC was investigated by FTIR, HNMR, FESEM, TGA ...
