用便携式微机伏安仪对贵金属Pd的电化学性能和测定进行了研究。在1 mol/L HCl溶液中Pd(Ⅱ)浓度2.5ng/ml～60μg/ml范围峰高是线性增加的。回收范围82％～105％。相对标准偏差为(n=8)3.8％。本法应用于贵金属回收液中Pd的测定,获得较为满意的结果。
The electrochemical performance and determination of Pd were studied by portable microcomputer voltammetry. In 1 mol / L HCl solution, the peak height of Pd (Ⅱ) in the range of 2.5ng / ml ~ 60μg / ml increased linearly. Recycling range of 82% to 105%. The relative standard deviation was (n = 8) 3.8%. This method is applied to the determination of Pd in the precious metal recovery solution, obtaining more satisfactory results.
