| Abstract | ||
| Zeolite adsorbs large amounts of dissolved ions in waters, its porous structure and high ionic exchange capacity makes it capable of removing impurities from wastewaters. Solutions were prepared by dissolving the respective compounds in the required amounts of distilled water and were filtered through a packed column of zeolite of known mass and volume. The initial concentration of each of the metals was as follows: Zn2+ (50 mg/L), Mn2+ (20 mg/L), Pb 2+ (50 mg/L), Fe 2+ (150 mg/L), Ca 2+ (200 mg/L), Cu2+ (150 mg/L), NH+4 (100 mg/L), PO3-4(80 mg/L) and NO-3 (20 mg/L). Removal capacity of zeolite in removing co-existing Zn2+ , Mn2+ and Pb 2+ was found to be 6.46, 3.3 and 13.84 (g metal ion/ kg zeolite) respectively and for removing co-existing Fe2+ , Ca2+ and Cu2+ was 21.96, 40.26 and 24.7 (g metal ion/ kg zeolite) respectively whereas for removing co-existing NO-3 , NH+4 and PO3-4 was 4.75, 17.8 and 20.57 (gm group-ion/ kg zeolite) respectively. In this study zeolite was proved to be an effective material in removing co-existing metals ions and ion-groups from wastewater. | ||
