摘要:
在773 K氩气环境下,采用CP熔盐电化学方法对LiCl-KCl电解质体系中不同组分LaCl3(0.98 %、2.0 %和3.3 %)进行La离子浓度检测.结果表明:La(Ⅲ)在钨电极上相对于银/氯化银参比电极的还原析出电位在-2.0~-2.2 V左右,通过阴极峰电流值、过渡时间与深度三者关系计算,773 K下La离子扩散系数在1.29×10-5~5.42×10-5 cm2/s之间.通过对比计时电位法(CP)和电感耦合等离子体原子发射光谱法(ICP)检测的La离子浓度结果,相对误差依次为1.25 %、1.11 %和1.72 %.LiCl-KCl熔盐中La电沉积的峰值电流和过渡时间平方根的乘积与浓度呈良好线性关系,说明以CP熔盐电化学方法检测离子浓度可行性好.
