Study of the malachite green removal by modified and pilliared algerian clays: optimization and performance

Abstract

Dyes are organic compounds widely used in the food and cosmetics fields, as well as in industry, particularly textile dyeing because of their chemical stability, ease of synthesis and their variety of colors. They are unfortunately one of the main sources of pollution in water even in very small quantities, is very visible and undesirable. This work concerns the study of the dye removal present in textile effluents. The study of the elimination kinetics of malachite green has shown that the reaction is rather fast, the adsorption maximum is reached within 30 min for ANa with the adsorption yield 96.69% and 5 min for ANM with adsorption yield 99.2%. The adsorption process is controlled by the kinetic model of the pseudo second order...
