ADSORPTION DES COLORANTS TEXTILES PAR UNE ARGILE MODIFIEE

Abstract

In this work we proceeded to the determination of the structural and physico - chemical features of clay in order to study his behavior screw to screw of certain textile stains of synthesis. We prepared different samples cationics (Na+, Al+3, Fe+3) and another treaty by H2O2. The bruise of methylene acted as model. Isotherms of adsorption have been studied according to several physico-chemical parameters: pH, granulometry, temperature and speed of agitation. Parameters of the adsorption balance gotten according to the equation of Langmuir have been determined. The experimental results show that the clay treated by H2O2 and NaOH presents features of adsorption favorable to the elimination of this synthesis stains textile.
