EMD在Pb-Ag-Ca新型合金阳极上电沉积杌理研究

RESEARCH ON EMD OF ELECTRO-DEPOSITION MACHANISM ON THE Pb-Ag-Ca NEW ALLOY ANODE (PAC ANODE)

根据对在实际电解条件下的电解液的吸收光谱谱图的测定,确定了在电解反应过程中有Mn^(3+)和MnO_4^-等生成。据此,可认为电解二氧化锰沉积(EMD)机理首先为各种价态的Mn离子在不同甲下的反应为(3)(4)(5)式,电解液最终存在如下平衡。 2Mn^(3+)+2H_2O=MnO_2+Mn^(2+)+4H^+ ΔG=-108.76K_J (1)

From the determination of absorption Specturm of electrolyte in a practicably electrolytical process in which form the Mn3+ and MnO4- ions ,the auther affirm the machanism of EMD electro-deposition is (3)(4X5) formula ,and established the equilibrium of electrolyte finally.2Mn3++2H2O=MnO2+Mn2+4H+ G=-108.76KJ(1)
