Sorption studies on clay for the removal of phenol and p-nitrophenol from aqueous solution

Abstract

620-623Sorption of phenol and p-nitrophenol from aqueous solution has been investigated using clay sorbent. The effect of particle size of sorbent, pH, phenol concentration and temperature on sorption capacity has been studied by batch experiments. Langmuir adsorption isotherm constants show that the sorption data for phenols onto clay fits well in this model. The sorption of phenols studied follows pseudo second-order kinetics. This study shows that clay can be used as an efficient sorbent material for the sorption of phenols from aqueous solution
