Calculation of the Thermodynamic Parameters of Adsorption of the Pesticides (Rodazine) in Aqueous Solution by Natural and Modified Clays

Abstract

The purpose from this works is to test two clays, first Bentonite and the clay of Djebel Debbagh as well as bentonite coupled with cellulose within the framework to eliminate pollution: pesticide (the Rodazine). Bentonite-cellulose is selected as the argillaceous material which has a capacity raised for the adsorption of the organic pollution used. The study is to influence the experimental parameters (pH, temperature and stirring velocity) on the power adsorbents of the clays studied with respect to the pollution used. Our works are closed by kinetic, thermodynamic modelings and the isotherms of adsorption. The results showed the practical interest of the use of clay in the field of the pollution of the water contaminated by the organic pollution.
