Removal of heavy metals from wastewater with Bigadic (Tuerkiye) clinoptilolite
- Osmangazi Univ., Eskisehir (Turkey). Mining Engineering Dept.
In this study, Bigadic upper zone zeolitic tuff, which contains about 87% clinoptilolite was used as an ion exchanger for removal of Pb{sup ++}, Cu{sup ++}, Cd{sup ++} and Hg{sup ++}ions from wastewater. Bench scale experiments with two different glass columns, were carried out continuously under the closed/open circuit conditions. Before ion exchange tests, zeolite samples were treated with NaCl (6ml/min. and 42BV). The effects of particle size, bed volume, pH and flow rate on the ion exchange capacity were determined. Under the best operation conditions, the effect of initial influent solution concentration on ion exchange selectivity was tested. As a result, it was found that the Bigadic clinoptilolite had the following ion exchange capacities; Pb{sup ++}, 0.7540 meg/g; Cu{sup ++}, 0.6986 meg/g; Cd{sup ++}, 0.6580 meg/g; Hg{sup ++}, 0.5530 meg/g.
