A synergistic combination of chloride and copper powder was proposed as a new method to reductively remove arsenic from highly-,acidic wastewater with high arsenic content, (HAWA). As(III) was reduced to As(0) by copper powder in the presence of chloride and were effectively removed from HAWA. The procedure to remove arsenic was optimized as follows: initial H ,concentration, of
