Use of natural zeolites for lead pollution removal from water

A natural zeolite, Clinoptilolite was used to investigate its adsorption capacity for the lead (II) ions from artificial polluted tap water in this study. For the experimental studies, Clinoptilolite mineral which is 25-140 mesh size was used by activating with HCl, and lead ion removal efficiencies were examined. Experiments were studied under laboratory batch conditions were run at different pH values, temperatures. The highest removal efficiency was found as about 87% at pH 5. Similarly, experiments were carried out at different temperature values, and the maximum efficiency was obtained at 30°C. The efficiency obtained under these conditions was 89.95%. The highest lead removal efficiency was obtained with 200 rpm shaking speed.
