摘　　要：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 behaviour and determination of palladium is investigated with portable computerized voltammeter. The height of the peak was linearly increased ith the concentration of Pd (Ⅱ) over the range of 2.5ng/ml～60μg/ml in a solution of lmol/L HCI. Its recovery is in the range from 82％ to 105％. The relative standard deviation (n=8) is 3.8％. The method has been applied to the determination of palladium in retrieval solution of precious metals with satisfactory results.
