Flocculation of Kaolin Suspension with Graft Copolymers of Chitosan.

Hydrogels based on modified chitosan, 1. Synthesis and swelling behavior of poly(acrylic acid) grafted chitosan

“…Chitin (poly-b(1e4)-N-acetyl-D-glucosamine) is distributed widely in nature forming the principal constituent of shells of crustaceans such as crabs, lobsters, prawns, Antarctic krill, etc. Recently chitosan has attracted great attention because the range of its applications has been extended, among other uses, to medical [25][26][27][28][29] , wastewater treatment [30][31][32] , membranes [33][34][35][36] , flocculants 37,38) , etc. Chitin is structurally similar to cellulose, containing an acetamido group instead of the C-2 hydroxyl group.…”
