Abstract
Abstract The landfill leachate contains high level of heavy metals which ultimately contaminate either groundwater, surface water or both owing to infiltration and surface runoff. These heavy metals have no useful role in human life and may be toxic even at trace concentration and ultimately causes serious health concern. Thus the removal of heavy metals from landfill leachate is necessary and one of the effective ways to minimize the further contamination. In this article Kaolinite is used as an adsorbent to remove lead and copper ions through the batch adsorption process. The maximum removal efficiency of 81.96% was observed for lead and 57.58% for copper with 20 g/l of kaolinite. Thus, it can be observed that kaolinite has a good potential to be used for the removal of heavy metal ions from landfill leachate as it is cost effective, abundant and easily available adsorbent.
期刊介绍：
The Environmental Claims Journal is a quarterly journal that focuses on the many types of claims and liabilities that result from environmental exposures. The ECJ considers environmental claims under older business insurance policies, coverage and claims under more recent environmental insurance policies, as well as toxic tort claims. Exposures and claims from all environmental media are considered: air, drinking water, groundwater, soil, chemicals in commerce and naturally occurring chemicals. The journal also considers the laws, regulations, and case law that form the basis for claims. The journal would be of interest to environmental and insurance attorneys, insurance professionals, claims professionals, and environmental consultants.
