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. This method is generally applied in biotechnology and in medical field for checking out the protein and DNA. Now it can be applicable in Environmental Engineering field.

In the previous papers presented they have separated heavy metals like cobalt, gold, nickel, lead, iron, zinc etc. 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.

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.
