三价铬离子在电沉积过程中的形态

Species of Trivalent Chromium in the Bath for the Electrodeposition of Chromium

    摘要
  • 摘要: 研究证明三价铬离子在HCl体系中适应电活性物质是Cr(H2O)63+,不同pH通过溶液中的存在形态而影响Cr3+电沉积过程。同时证实了Cr3+在HCOOH或(NH2)2CO存在时不与三价铬形成配位化合物。

     

    Abstract: The species of the trivalent ions of chromium in the HCl containing systems have been studied. The proper electroactive species was found to beCr(H2O)63+. The electrodepostion of chromium was found to be strongly affected by the pH of the bath due to the different species of trivalent chromium at different pH, and coordination compounds of Cr3+ with HCOOH or(NH2)2CO were not found.
