Research on the Adsorption of Cu2+,Zn2+ and Cd2+ with epiolite

摘要：

Sepiolite is a kind of clay minerals for fibrous silicate,it shows better adsorption because of its giant relative surface and the unique holestructure. The adsorption of Cu~(2+),Zn~(2+)and Cd~(2+)with clay minerals sepiolite was studied by isothermal adsorption test. The results showed that sepiolite had a high affinity for Cu~(2+),Zn~(2+)and Cd~(2+),he adsorption capacity was increased and the adsorption rate was reduced with the rising of initial concentration of Cu~(2+),Zn~(2+)and Cd~(2+),the adsorption mechanism was as well as studied at the same time.
