Ni^（2＋）、Fe^（2＋）和H_2PO_2~－、H_2PO_3~－在悬汞电极上的电化学行为

Electrochemical Behavior of Ni￣(2+)、Fe￣(2+)and H_2PO_2￣-、H_2PO_3￣- on Hanging Mercury Drop Electrode

采用循环伏安法研究了Ｎｉ２＋、Ｆｅ２＋、Ｈ２ＰＯ２－Ｈ２ＰＯ３－在悬汞电极上的电化学行为以及Ｈ２ＰＯ２－、Ｈ２ＰＯ３－在ＫＣＬ支持电解质中的还原机理，对电沉积Ｎｉ—Ｆｅ—Ｐ非晶态合金中磷的沉积机理有进一步的认识。

Electrochemical behavior of Ni2+.Fe2+.H2PO2- H2PO3- on hanging mercury drop electrode (HMDE) and reduction mechanism of H2PO2- H2PO3-in KCl supporting electrolyte are studied by means of cyclic voltammetry.Deposition mechanism of phosphorus is also discussed for Ni-Fe-P amorphous alloy electrodeposition.
