Removal of Binary Metal (Nickel and Lead) Ions from Aqueous Solution Using Natural and Modified Clinoptilolite


Article Preview

In this study, adsorption of binary metal (Ni(II) and Pb(II)) ions from aqueous solution by using natural (NC), acid-modified (AC) and base-modified (BC) clinoptilolite were investigated to determine the effects of adsorbent dosage, metal solution’s pH and initial metal solution concentration. From the adsorption studies, the optimum dosage of adsorbent was found to be 2.0g for all adsorbents (NC, AC and BC) specifically for removal of Pb(II). In contrast, optimum dosage of for removal of Ni(II) was found to be 2.0g for NC and 4.0g for both AC and BC, respectively. The average pH for Ni(II) and Pb(II) ion solutions were 6. It was further observed that, the percentage removal of Ni(II) was largely influenced by the presence of lead due to the preference of Pb2+ ions by the natural and modified clinoptilolites.
