All the tested salt solutions except Na2SiO3 enhanced ZVI corrosion to different extents. Dominant corrosion products derived from ZVI varied with the type of brine solution. Degrees of both H2 evolution and O2 adsorption corrosions were quantified. Removal of As/Se was positively correlated with the degree of ZVI corrosion. As/Se removal by pcZVI involved both the adsorption and reduction processes.
