In this paper, a silicas-supportedpolyethyleneimine resin is synthesized and its adsorption proper-ties are studied. Its selectivity of sorbing heavy metal ion will vary considerably as the pH value of solution varies. In hy-drochloric acid,the resin only sorbs Au(Ⅱ). This suggests that the resin is applicable to the separation of copper (Ⅱ) or gold (Ⅲ).展开更多
文摘Abstracts . In this paper, a silicas-supportedpolyethyleneimine resin is synthesized and its adsorption proper-ties are studied. Its selectivity of sorbing heavy metal ion will vary considerably as the pH value of solution varies. In hy-drochloric acid,the resin only sorbs Au(Ⅱ).
