The total eradication of environmental pollution has become impossible as this problem has magnified to a large scale. Pollution is one of the greatest abuses of our natural water resources. Excessive dumping of chemical waste containing heavy metals into water bodies, render the water useless for human needs. Most of the industries release untreated or partially treated effluent discharge into the nearby drains and water streams which contain heavy metals. Surface finishing and metal deposition are the important processes of electroplating industry which commonly use nickel, copper, zinc and chromium.[1].Wastewater generated from them release substantial quantity of heavy metal ions which leads to heavy metal pollution. In industrial, ground, marine, and even in treated wastewater, heavy metals are major pollutants. Heavy metals ions …show more content…

Almost, all heavy metals ingested beyond permissible quantities causes various chronic disorders in human beings. The effluents released from silver refineries, electroplating, zinc base casting and storage battery industries contain Ni. Acute poisoning of Ni (II) causes nausea, dizziness, headache, and vomiting, chest pain, rapid respiration, tightness of the chest, dry cough and short breath, cyanosis and extreme weakness. Higher concentrations of nickel cause cancer of lungs, nose and bone. The most frequent effect of exposure to Ni is dermatitis (Ni itch).[2]. Any industry using metals faces a problem of metal disposal. So some cleaner and advanced technologies are required for the treatment of heavy metal contaminated wastewater. To dispose the industrial effluents without danger to human health and damage to the
