| Abstract: | The preparation and adsorption to Hg~2+, Cd~2+,Cu~2+, Cr~6+, Pb~2+, Zn~2+, Ni~2+ of chitosanmodified by TDI are studied, The effects of pH, time and temperature on the adsorption are investigated. The results show that the modified chitosan is easy to be regenerated and less soluble in asidic solution and it has higher adsorption selectivity for Hg~2+, Cd~2+, Cu~2+ when Hg~2+, Cd~2+, Cu~2+, Cr~6+, Ph~2+,Zn~2+,Ni~2+ are present simultaneously in solution. |
