Use of methacrylic acid grafted poly(ethylene terephthalate) fibers for the removal of basic dyes from aqueous solutions
(John Wiley & Sons Inc, 2008)
A reactive fibrous adsorbent was prepared through the grafting of a methacrylic acid monomer Onto poly(ethylene terephthalate) fibers for the removal of basic dyes such as methylene blue and basic red 9 from aqueous solutions ...
Reversible immobilization of lipase on phenylalanine containing hydrogel membranes
(Elsevier Sci Ltd, 2001)
Poly(2-hydroxyethylmethacrylate-co-methacrylamidophenlyalanine) poly(HEMA-MAPA) membranes were prepared by UV-initiated photopolymerization of HEMA and MAPA. Lipase immobilization onto these membranes from aqueous solutions ...
Membrane with incorporated hydrophobic ligand for hydrophobic interaction with proteins: application to lipase adsorption
(Wiley, 2002)
In this study, phenylalanine as a hydrophobic ligand was covalently attached on a comonomer, methacryloyl chloride. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenylalanine), poly(HEMA/MAPA), membranes were ...
Removal of cadmium (II) from aqueous solumns using sporopollenin
(Parlar Scientific Publications (P S P), 2004)
Sorption of cadmium ion from aqueous solution by sporopollenin, a polymer obtained from Lycopodium clavatum, was investigated. The influences of adsorption time, temperature, pH of solution, and Cd(II) concentration on the ...
Adsorption of serum albumin and gamma-globulin from single and binary mixture and characterization of pHEMA-based affinity membrane surface by contact angle measurements
(Elsevier Science Bv, 2005)
In this study, an affinity membrane was synthesized using 2-hydroxyethylmethacrylate (HEMA) via UV-initiated photopolymerization. A dye-ligand (i.e., Procion Red HE-3B; Red-120) was covalently immobilized onto membrane. ...
Procion Brown MX-5BR attached and Lewis metals ion-immobilized poly(hydroxyethyl methacrylate)/chitosan IPNs membranes: Their lysozyme adsorption equilibria and kinetics characterization
(Pergamon-Elsevier Science Ltd, 2002)
Interpenetration networks (IPNs) in membrane form were synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan (pHEMA/chitosan) via UV-initiated photo-polymerization in the presence of an initiator alpha, ...
Novel hydrogel membrane based on copoly(hydroxyethyl methacrylate/p-vinylbenzylpoly(ethylene oxide)) for biomedical applications: Properties and drug release characteristics
(Wiley-V C H Verlag Gmbh, 2005)
The aim of this study was to synthesize and characterize a novel biocompatible polymeric membrane system and demonstrate its potential use in various biomedical applications. Synthetic hydrogels based on poly(hydroxyethyl ...
Ethylenediamine grafted poly(glycidylmethacrylate-co-methylmethacrylate) adsorbent for removal of chromate anions
(Elsevier Science Bv, 2005)
The removal of chromate anions (CrO42-) from aqueous solutions under different experimental conditions using cross-linked poly(glycidylmethacrylate-co-methylmethacrylate), poly(GMA-co-MMA), adsorbent was investigated in ...
Sorption behaviour of copper(II), zinc(II) and nickel(II) on formaldehyde cross-linked Saccharomyces cerevisiae immobilized on pumice stone
(Inst Lebensmitteltechnologie Analytische Chemie, 2001)
The adsorption of Cu, Zn and Ni on to formaldehyde cross-linked Saccharomyces cerevisiae immobilized on pumice stone was investigated. Maximum adsorption was occurred at pH 6 for all elements studied. The effect of mixing ...
Reversible immobilization of urease onto Procion Brown MX-5BR-Ni(II) attached polyamide hollow-fibre membranes
(Elsevier Sci Ltd, 2002)
Urease was immobilized onto Procion Brown MX-5BR attached and Ni(II) incorporated microporous polyarnide hollow-fibre membrane via adsorption. Urease immobilization onto the polyamide hollow-fibre membrane from aqueous ...
