Removal of Copper from Phosphoric Acid by Adsorption on Tunisian Bentonite

Abdennebi N, Bagane M and Chtara C

This experimental study was articulated around the efficiency of the technique of adsorption as a method for the elimination of copper from phosphoric acid by using bentonite as a support. Several parameters such as the effect of the initial concentration of the pollutant, the isotherms and the retention capacity of bentonite, was investigated. The adsorption was modeled by simples’ models of Langmuir, Freundlich. The results obtained have proved that the adsorption of copper follow the Freundlich Model.
