摘　　要：研究了（S）-N-苄基-2-吡咯烷-α，α-二苯基甲醇分光光度法测定Pd^2＋的条件，在酸性介质中，用十六烷基三甲基溴化铵（CTAB）作为表面活性剂，该试剂与Pd^2＋形成的物质的比为1：2，表观摩尔吸光系数为3．94×10^3L·mol^-1·cm^-1．线性范围为9．40×10^-6～3．25×10^-4mol·L^-1，该方法用于模拟试样中微量钯的测定，结果令人满意．In this paper, a new method for the determination of trace Pd^2＋ has been established. In the presence of sensitizer CTAB, the formation condition of （S）-N-benzyl-2-pyrrolidine-α,α-di-phenyl ethanol- Pd^2＋ compound and the compound have been studied in acid solution. Under the optimal conditions, the compound is 1：2 , is 3.94×10^3L·mol^-1·cm^-1 and the range of determination is 9.40×10^-6～3.25×10^-4mol·L^-1 The method developed in this paper has been applied to determine trace Pd^2＋ in simulated alloy successfully.
