Abstract

Simultaneous adsorption of phenol and phosphate(V) ions on the surfactant-modified clay from the binary mixture was studied and compared with the single phenol or phosphate(V) sorption. The maximum adsorption capacity of hexadecyltrimethylammonium–bentonite was 18.8 mg/g for phenol and 38.5 mg/g for phosphate(V) at simultaneous adsorption of both of them. The optimal pH values of adsorption on hexadecyltrimethylammonium–bentonite was found to be 7.0 and >7 for phosphate(V) and phenol, respectively. The kinetic studies showed that the adsorption followed a pseudo-second-order reaction for both. The equilibrium data were analyzed using the Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherm models.
