文摘

Branched noncharged copolymers Dextran-g-Polyacrylamide and their anionic derivatives were synthesized. Copolymers were tested as flocculants in model kaolin polydisperse suspensions. Suspension sedimentation rate and degree of supernatant clarification were studied at different flocculants concentration Analysis of the kinetics of flocculation process allows us to choose the most effective flocculant.
