Properties of immobilized tannase (ITA) were studied.

Immobilized tannase which had higher ability of transforming tannin from Chinese gallotannin into GA was prepred by embedding tannase with calcium alginate carrier.

Immobilized tannin, a novel polymer, was synthesized by coupling tannin with macroporous spherical cellulose.

Immobilized tannin using plant cellulose as a carrier and natural tannin as a genin is a new-type cova-lently-bonded adsorbent.

Preparation of a new immobilized tannins macroporous adsorption resin;

This thesis investigated the adsorption behaviours of Cd(II), V(V) and Cr(VI) on the adsorbents based on collagen fiber, including collagen fiber immobilized tannins and Zr(IV)-impregnated collagen fiber.

A new macroporous adsorption resin immobilized tannins was prepared by immobilizing tannins on styrene-divinylbenzene copolymer using Mannich reaction, based on reviewing the present researches of adsorption resin and the functional polymers of plant tannins.

Preparation of collagen-immobilized tannin membrane and its adsorption to U(Ⅵ);

Using collagen fibre as matrices,the immobilized tannins adsorbents based on black wattle,larch and myrtan tannins were prepared through crosslinking reaction.

Based on the mechanism of vegetable tannins–aldehyde combination tannage in leather-making, a kind of novel immobilized tannin membrane was prepared through cross-linking reaction of oxazolidine between condensed tannins and collagen fibers.

Application of immobilized enzyme in food industry;
