The release of toxic effluents from a variety of sources into the environment has become a major worldwide concern. One of the main ingredients in these undesirable industrial effluents is heavy metals. Although heavy metals are naturally occurring components of the earth's crust, human activity has significantly changed the geochemical cycles and biological balance of these elements. Heavy metals are mostly found in the effluent of certain sectors, including electroplating, paints, plastics, tanneries, and batteries. The government and other public sectors are developing strategies and putting various techniques into practice to properly mitigate the pollution caused by heavy metals. Conventional methods of extracting metals are often expensive and dangerous due to the potential for producing toxic byproducts. Additionally, those methods of treatment (which are primarily chemical and physical and include reverse osmosis, chemical precipitation, ion exchange, and evaporative recovery).
