A REVIEW ON REMOVAL OF HEAVY METALS BY USING LOW COST ADSORBENTS WITH REFERENCE TO ELECTROPLATING INDUSTRY
Main Article Content
Abstract
The industrial wastewater from silver processing at Hupari is not provided with any treatment system for removal of heavy metals. Same wastewater is discharged to the sewage system and any sewage system has not any provision of removal of heavy metal.The issue of heavy metal pollution is very much concerned because of their toxicity for plant, animal and human beings and their lack of biodegradability. Excess concentrations of heavy metals have adverse effects on plant metabolic activities hence affect the food production, quantitatively and qualitatively. Heavy metal when reaches human tissues through various absorption pathways such as direct ingestion, dermal contact, diet through the soil–food chain, inhalation and oral intake may seriously affect their health..The greatest damage to the environment is made by metal compounds that are washed out in wastewater from the electroplating industry
