Adsorption studies of volatile organic compound (naphthalene) from aqueous effluents: Chemical activation process using weak Lewis acid, equilibrium kinetics and isotherm modelling

This study deals with the preparation of activated carbon (CDSP) from date seed powder (DSP) by chemical activation to eliminate polyaromatic hydrocarbon-PAHs (naphthalene-C10H8) from synthetic wastewater. The chemical activation process was carried out using a weak Lewis acid of zinc acetate dihydr...
