Abstract: Effects of different reducers as well as various reaction conditions on reducing of hexavalent chromium were investigated. The reaction process was discussed and the optimum reaction conditions were determined. The reaction product can serve as chromium source of nontoxic chromium plating and coating thicker than 100μm was obtained.
