Adsorption of Pyrene from Aqueous Solution by Clay and Sandy Soil


The adsorption behaviour of pyrene using clay and sandy soil under ambient conditions is investigated in this study. Adsorption equilibrium isotherms and adsorption kinetics experiments were carried out in solutions of pyrene concentrations (50 - 250 mg/l) by using clay and sandy soil as adsorbents. Adsorption models were used to predict the mechanisms involved. The adsorption kinetics data best fitted the pseudo-second order kinetic model. The isotherm model which best represented the data obtained was the Langmuir model. The adsorption from the aqueous solution was observed to be time dependent and equilibrium time was found to be 34 and 28 hours for clay and sandy soil, respectively. The rate of adsorption using the pseudo-second order rate expression for pyrene was 0.00088 and 0.00085 min-1 for clay and sandy soil, respectively.
