摘要
用线性扫描电位法研究 Ho^(3+).Eu^(3+)在氯化物熔体中还原的电极过程,Ho^(3+)在钨、钼电极上进行可逆3电子还原为 Ho 的反应.Eu^(3+)在钨、钼、铂电极上第一步可逆还原为 Eu^(3+),在铂电极上 Eu^(2+)进一步还原并与铂形成合金.测定了 Ho^(3+),Eu^(3+)在氯化物熔体中的扩散系数.
The linear scanning voltammetry has been used to study the electrode processes of Ho^(3+),Eu^(3+)in molten chlorides.The reversible three-electron reduction of Ho^(3+)to Ho was proceeded on W or Mo electrode.The reduction of Eu^(3+)to Eu^(2+)was re- alized on W,Mo and Pt electrodes,respectively,at the first step.Eu^(2+)was subjected to reduction and formed alloy with Pt on Pt electrode.The diffusion coefficients of Ho^(3+),Eu^(3+)in molten chlorides have been determined.
