Preparation, characterization, and application of polypropylene-clinoptilolite composites for the selective adsorption of lead from aqueous media

► A clinoptilolite-polypropylene composite for adsorption of lead has been prepared. ►The activation of clinoptilolite before mixing with polypropylene was essential. ► The mechanical strength of polypropylene was not affected by the activation process. ► The adsorption and desorption of lead from aqueous media have been successful. ►The composite can thus be used on a routine basis in water purification systems.
