26/3/2018, · Strongly acidic wastewater (H2SO4) with a high arsenic concentration is produced by many industries. The removal of arsenic by traditional sulfide (e.g., Na2S, FeS) from strongly acidic wastewater introduces cations (Na+ and Fe2+) to the solution, which may prevent the recycle of acid. In this study, a new sulfuration agent, phosphorus pentasulfide ...
