The removal experiments of the heavy metal ions in the water: Cd2+ , Hg2+ , Pb +, As , Mn2+ , Ni2+ , Cr6+ and Cu2+ were carried out by post exchange with the azotic cellulose and carbomethyl cellulose, which obtained a better satisfactory removal effect.

• 并用其通过柱交换对水中的Cd~(2+)、Hg~(2+)、Pb~(2+)、As~(3+)、Mn~(2+)、Ni~(2+)、Cr~(6+)、Cu~(2+)等重金属离子分别进行了去除实验,取得了较为满意的去除效果。
