Study on the Adsorption of Copper Ions by Bentonite

Abstract:

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.
