摘    要:用DDO为捕收剂,CTMAB为助浮剂,在SnCl_2存在下,以石油醚+氯仿+正戊醇(3+2+5)混合溶剂为有机溶剂,经溶剂浮选用分光光度法测定痕量钯,其检测下限为0.14μg/200ml,钯的回收率接近100%。大多数贱金属离子不干扰钯的测定。

关 键 词:钯,溶剂浮选,分光光度法

Abstract:A method for determining trace palladium is developed based on the complex formed by Pd(Ⅱ)and didodecyldithiooxamide and cetyltrimethylammonium bromide in the presence of SnCl_2.The mixture of benzinum and chloroform and n-amylic alcohol in volume ratio of 3:2:5 is used asorganic phase. The detection limit is 0.14μg/200ml.The recovery of Pd is between 98.80% 101.3%.Under the experimental conditions,the majority of base metal ions do not interfere withthe determination.
Keywords:palladium  solvent sublation  spectrophotometry
