Separation and speciation of Cr(III) and Cr(VI) with Saccharomyces cerevisiae immobilized on sepiolite and determination of both species in water by FAAS
(Elsevier Science Bv, 2000)
A rapid, sensitive and accurate method for the separation, preconcentration and determination of Cr(III) and Cr(VI) in water samples is described. Chromium species can be separated by biosorption on Saccharomyces cerevisiae ...
Determination of Cu, Zn, Fe, Ni and Cd by flame atomic absorption spectrophotometry after preconcentration by Escherichia coli immobilized on sepiolite
(Elsevier Science Bv, 2000)
A method for the determination of Cu, Zn, Fe, Ni and Cd by flame atomic absorption spectrophotometry (FAAS) after preconcentrating on a column containing Escherichia coli immobilized on sepiolite has been developed. Optimum ...
Preparation of reversibly immobilized lysozyme onto Procion Green H-E4BD-attached poly(hydroxyethylmethacrylate) film for hydrolysis of bacterial cells
(Elsevier Sci Ltd, 2001)
The flat sheet support for enzyme immobilization was prepared by UV-initiated photopolymerization of 2-hydroxyethyl-methacrylate (HEMA) in the presence of an initiator (alpha alpha'-azoisobutyronitrile. AIBN). An affinity ...
Immobilization of catalase via adsorption onto L-histidine grafted functional pHEMA based membrane
(Elsevier Science Bv, 2001)
Poly(2-hydroxyethylmethacrylate) (pHEMA) based flat sheet membrane was prepared by UV-initiated photopolymerization technique. The membrane was then grafted with L-histidine. Catalase immobilization onto the membrane from ...
Reversible immobilization of tyrosinase onto polyethyleneimine-grafted and Cu(II) chelated poly(HEMA-co-GMA) reactive membranes
(Elsevier, 2004)
The present study describes the preparation of poly(HEMA-co-GMA) reactive membranes that were grafted with polyethylenimine (PEI) following UV photo-polymerization. The immobilization of tyrosinase was carried out via ...
Immobilization of a thermostable α-amylase onto reactive membranes: kinetics characterization and application to continuous starch hydrolysis
(Elsevier Sci Ltd, 2004)
Epoxy groups containing porous membranes were prepared by UV-initiated photopolymerisation of hydroxyethylmethacrylate (HEMA) and glycidyl methacrylate (GMA). Epoxy supports could provide multipoint covalent attachment of ...
Polyethyleneimine-grafted poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible glucose oxidase immobilization
(Elsevier Science Sa, 2004)
Glucose oxidase (GOD) was immobilized onto polyethyleneimide (PEI) grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-co-GMA)) membranes. The maximum GOD immobilization capacities of the ...
Ca-alginate as a support for Pb(II) and Zn(II) biosorption with immobilized Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2003)
The basidio spores of Phanerochaete chryosporium were immobilized in alginate gel beads, and the immobilized spore containing alginate beads were incubated for the growth of fungus. The biosorption of Pb2+ and Zn2+ ions ...
DNA adsorption on a poly-L-lysine-immobilized poly(2-hydroxyethyl methacrylate) membrane
(Wiley, 2003)
The DNA adsorption properties of poly-L-lysine-immobilized poly(2-hydroxyethyl methacrylate) (pHEMA) membrane were investigated. The pHEMA membrane was prepared by UV-initiated photopolymerization and activated with ...
Poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) reactive membrane utilised for cholesterol oxidase immobilisation
(John Wiley & Sons Ltd, 2002)
Poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) p(HEMA-GMA) membrane was prepared by UV-initiated photopolymerisation of 2-hydroxyethyl methacrylate (HEMA) and glycidyl methacrylate (GMA) in the presence of an ...
