Chitosan-polyacrylamide graft copolymers prepared with gamma irradiation for gold cyanide adsorption

Cyanidation is one important process in gold mining industries that required proper methods for gold recovery. The present study aims to explore gold cyanide adsorption using chitosan-polyacrylamide graft copolymers synthesized by gamma irradiation. The effects of pH, gold cyanide concentration, and adsorption time were evaluated. The FTIR analysis shows that grafting of polyacrylamide onto chitosan has been obtained. The results indicated that...
