چکیده:

The effects of varying operating conditions on metals removal from aqueous solution using a novel platinum nanopartcles/Zeolite-4A adsorbent are reported in this paper. Characterization ofthe adsorbent showed successful production of platinum nanopartcles on Zeolite-4A using 3 Wt% platinum. The effects of operation conditions on metals removal using this adsorbent wereinvestigated. Experimental conditions resulting in optimal metals adsorption were observed at pH 7, 0.1 g/10mL dosage and 30 min contact time. Sorption data have been interpreted in terms ofLangmuir and Freundlich isotherms
