Arsenic removal by electrocoagulation process: Recent trends and removal mechanism
Arsenic contamination in drinking water is a major issue in the present world. Arsenicosis is the disease caused by the regular consumption of arsenic contaminated water, even at a lesser contaminated level. The number of arsenicosis patients is increasing day-by-day. Decontamination of arsenic from the water
medium is the only one way to regulate this and the arsenic removal can be fulfilled by water treatment
methods based on separation techniques. Electrocoagulation (EC) process is a promising technology for
the effective removal of arsenic from aqueous solution. The present review article analyzes the perfor-
mance of the EC process for arsenic removal. Electrocoagulation using various sacrificial metal anodes
such as aluminium, iron, magnesium, etc. is found to be very effective for arsenic decontamination. The
performances of each anode are described in detail. A special focus has been made on the mechanism
behind the arsenite and arsenate removal by EC process. Main trends in the disposal methods of sludge
containing arsenic are also included. Comparison of arsenic decontamination efficiencies of chemical
coagulation and EC is also reporte
