Abstract
Electrocoagulation (EC) is a significantly efficient method for As removal from waters and received considerable attention recently. In this study, the natural groundwater (GW) samples containing As concentrations of GW-1: 538.8 g L 1 , GW-2: 1132.1 g L 1 , and GW-3: 52, 000 g L 1 were obtained from different provinces and treated by EC process using different iron anodes (plate, ball, and scrap). To achieve drinking water As standard (10 g L 1 ), the operational time, applied current, and As removal optimization for all anode types were studied.
