Abstract

The toxic heavy metals such as cadmium, copper, lead, nickel, mercury, and zinc from aqueous environment has received considerable attention in recent years due to their toxicity and carcinogenicity. This paper focuses mainly on Nickel & Mercury which may cause damage to various systems of the human body. Mercury and Nickel ions are non-biodegradable toxic heavy metals and may cause dermatitis and allergic sensitization. The major sources of Nickel & Mercury contamination to water comes from industrial process such as electroplating, batteries manufacturing, mine, metal finishing and forging. Different methods were investigated and applied to remove nickel and mercury ions from water such as adsorption, chemical precipitation, ion exchange, filtration, membrane separation, and reverse osmosis. In this paper a detailed insight has been given on adsorption with an eye on removal of mercury and nickel using different adsorbents.
