Adsorption of commonly drug from aqueous solution by natural and modified zeolite

This paper describes studies of evaluating natural and surface modification of a clinoptilolite zeolite with cetyltrimethyl ammonium chloride (CTAC), to investigate the adsorption efficiency for the removal of commonly drug from aqueous solution at bench scale. Modification of the zeolite with cationic surfactant (named ZMS) was based on the external cation exchange capacity.
