| Abstract: | Adsorption kinetics of Cu2 and Ni2 in smelting wastewater with 6 kinds modified bentonite prepared in laboratory was studied. The results show that adsorption of modified bentonite on Cu2 and Ni2 reaches adsorption equilibrium with 40 min. This adsorption accords with quasi-secondary dynamics model, and its reaction rate is directly proportional to square of reactant concentration. |

| Keywords: | modified bentonite adsorption kinetics Cu2 Ni2 |
