Immobilization of urease using glycidyl methacrylate grafted nylon-6-membranes

Synthesis and endotoxin removal properties of a novel affinity sorbent with poly(1-vinylimidazole) as the ligand

“…When the PVI grafted degree exceeded 16.7 wt%, the VI concentration increase in the reaction solution accelerated the homopolymerization, rather than graft polymerization, of the VI monomer, which led to the decreased PVI grafted degree with the increase of the VI concentration on the silicon gel. A similar phenomenon has been reported by Fu [17] and Teke and Baysal [18].…”

Characterization of Candida rugosa lipase immobilized onto magnetic microspheres with hydrophilicity

“…Coupling reactions involving epoxy groups and -NH 2 groups of enzymes had been widely reported [19][20][21]. The microspheres (1.0 g) were equilibrated in 50 ml phosphate buffer (0.1 M, pH 7.0) for 24 h. It was then transferred to the same fresh buffer (50 ml) containing CRL (0.1 g).…”

Sorption of acid and basic dyes on radiation-grafted Teflon scrap: equilibrium and kinetic sorption studies

“…Various desired functional groups can be introduced onto the bulk polymer via the addition reaction of epoxy groups with amine derivatives and sodium sulphite, which is promising for applications of heavy-metal ion extraction [24,25], enzyme immobilization [26], and specific protein adsorption and dye removal [27] from wastewater effluents.…”
