Modélisation des paramètres de l’adsorption compétitive des couples (Pentachlorophénol/Toluène) et (Pentachlorophénol/Xylène) sur des adsorbants à basse d’une argile Algérienne

Abstract

The objective of this work is the study of the in fluence of the presence of pentaclorophenol PCP on the competitive adsorption of to lueneandxylene of the Toluene/PCP and Xylene/PCP molar ratio on an Algerian clay intercalated with iron andmodifiedbyCTAB cetyltrimethyl ammonium bromidemolecules. ThepreparedmaterialsarecharacterizedbeforeandafteradsorptionbyFourierTransformInfrared Spectroscopy(IRFT). The adsorption kinetics of Toluene, Xylene and PCP are second order (R 2 >0.99). In binary systems the adsorption of toluene on the two matrices Bentonite-Fe-CTABand Mont-Fe-CTAB in the presence of PCP increases with the toluene / PCP ratio and there tention of xylene on these two matrices decreases with the xylene/PCP.
