Study on the Adsorption of Copper Ions by Bentonite
Bentonite was used as an adsorbent for removing copper ions from aqueous solutions，and the kinetic experiments and isothermal were performed. The results showed that the bentonite on Cu2+ adsorption followed the pseudo-secondary kinetic model, the high temperature was benefit for adsorption; The isothermal experimental data were fitted using Freundlich and Langmuir adsorption isotherm.
