The work carried out in this manuscript aims to test three clays: bentonite from Maghnia, kaolin from Mila and feldspar from Guelma (Algeria) in the context of removing organic pollutants: dyes (Bimacid Red and Dianix Blue). The bentonite is selected as the clay material that has a high capacity for adsorption of organic pollutants used. The study is followed by the influence of the experimental parameters (pH, temperature and agitation speed) on the adsorption capacity of the studied clays towards the used pollutants. Our work is closed by kinetic, thermodynamic and diffusional modelling. The…mehr

The work carried out in this manuscript aims to test three clays: bentonite from Maghnia, kaolin from Mila and feldspar from Guelma (Algeria) in the context of removing organic pollutants: dyes (Bimacid Red and Dianix Blue). The bentonite is selected as the clay material that has a high capacity for adsorption of organic pollutants used. The study is followed by the influence of the experimental parameters (pH, temperature and agitation speed) on the adsorption capacity of the studied clays towards the used pollutants. Our work is closed by kinetic, thermodynamic and diffusional modelling. The obtained results showed the practical interest of the use of clays in the field of the depollution of waters contaminated by organic pollutants.
