Abstract
LAS is the basic material in the industry of liquid and solid detergents, the adsorption of LAS achieved in the concentration 50-1000 mg.l-1. The adsorption efficiency on bentonite was modified using a cationic surfactant which is Cetyl Pyridinium Bromide (CPB), that raised the adsorption percentage Q(%) from 36% for free bentonite to 81% for modified bentonite at 298 K using 250 ppm LAS solution. The effect of adding three kinds of inorganic salts was studied; the salts were Pb(NO3)2, MgSO4, and CaSO4 in the concentration range (100-400) mg.l-1, The results showed a negative effect on the sorption process. The effect of pH on the sorption of LAS on clay showed that the highest sorption on bentonite was at pH 9, The thermodynamic parameters were calculated, and the kinetics were studied and it followed a pseudo-1st order kinetics.
