Electrochemical Removal of Organic Pollutants

Radioactive contamination at several sites due to improper handling of nuclear wastes and production and operation of nuclear fuel and nuclear reactors is well known (Chapter 5). The principal among radioactive materials are the following isotopes °Co, Sr, °Y, Ru, Ce, Pm, Pu, Ra, and so on, and 

Earlier efforts proved that the volatile and/or soluble organic contaminants are relatively easily removed by electroremediation, as well as by other conventional remediation technologies. Recent focus has been on electroremediation of hydro-phobic and persistent (hard to degrade) toxic compounds such as polycyclic aro-matichydrocarbons (PAHs), polychlorinatedorganiccompounds [e.g.polychlorinated biphenyls (PCBs)], pesticides, herbicides, and energetic compounds in soils. Several 

Sites contaminated by chlorinated pesticides (e.g. dichlorodiphenyltrichloroethane (DDT), aldrin, dieldrin, and endrin) and herbicides (e.g. atrazine, molinate and bentazone) due to agricultural activities and accidental spills have received little attention (Chapters 11 and 12). These contaminants are nonpolar in characteristics and sorb strongly to the soil. Similar to other hydrophobic organic compounds, desorption using solubilizing agents such as surfactants and cosolvents as well as
