摘要

Sodium alginateg-g-polyacrylamide(SAG) was synthesized by ceric ion induced redox polymerization technique.Six grades of graft copolymers were prepared by varying as well as monomer concentrations.The graft copoymers were characterized by intrinsic viscosity measurements,IR,and ~(13)C-NMR spectroscopies.Of the above grades,the graft copolymer of grade six(SAG-VI) which has longer polyacrylamide chains,was used for flocculation study.Two coking and noncoking coal fine suspensions were selected for the folcculation study .The flocculation performance of the graft copolymer was compared with commercial flocculants.In all cases,it was found that the graft copolymer showed better performance than the commercial flocculants.
