HEAVY METAL IONS DEPOLLUTION BY MARINE NATURAL PRODUCTS
Journal Title: Journal of Science And Arts - Year 2010, Vol 12, Issue 1
Abstract
Many industrial processes produce large amounts of wastewater, which have detrimental effects on human life and environment. The major pollutants in wastewater and marine ground are heavy metals such as lead, zinc, copper, cadmium, mercury, chromium and arsenic. These metals accumulate in living tissues/organs and can cause accumulative poisoning and serious health problems such as cancer and brain damage. Algae have been found to be potential suitable biosorbents due to their cheap availability, relatively high surface area and high uptake capacity. Algae are able to eliminate different forms of heavy metals by chelating, complexed formation, catalysis or adsorption [1,2]. In the present study, we used green algae as biosorbent. It has been studied the adsorption kinetics of metal ions using marine plants from synthetic solutions over different time intervals and various concentrations. The results have been processed by ICP-AES spectroscopy.
