Abstract

Electrokinetics is a rapid & simple method applied for separation of metal ions from wastewater. Basically based on electrical potential along with anode and cathode. In the previous papers presented they have separated heavy metals like cobalt, gold, nickel, lead, iron, zinc etc (1). In Electrophoresis process metals are separated by using high voltage as 10 kV (kilo volts) to 30 KV. In the studies the metal extraction is done in acidic condition. Much literature is not available on the Electro-kinetics technique for reference. All the metals separation from wastewater which is in ion form is separated by using chemicals and reagents (2, 3, 5). In the paper of Electro-coagulation the research is based on coagulation process and ampere based not voltage based. And other is based on high voltage separation called Electrophoresis. By Electrophoresis technique metal extraction is possible up to 95%, but this method is known as the Capillary Zone Electrophoresis. Various combinations of the time and voltage are applied in the available literature. Electrodes used for this study is having higher conductivity as silver and granite & so on.
