Many industries sometimes emit harmful products for the environment. Hexavalent chromium is regulated, but there are uses that cannot be substituted, mainly used for plating, leather product processing, cement hardening materials and so on. There is also still report of soil contamination of Cr (VI) in Japan all over the country. Thus, the toxicity of chromium compounds predominantly depends on oxidation states of chromium ions, and well-found and stabilized states are Cr (VI) and Cr (III). Solubility and toxicity of Cr (VI) compounds are higher than that of Cr (III) and the latter is usually readily immobilized by precipitation. Thus, reduction of Cr.. View More»
