一、在乙二胺四乙酸二钠盐掩蔽下可以避免许多阳离子对用5-亚氨基噻唑啉-2-硫代甲酰胺检定钯的干扰。二、本试剂与钯的生成物经各种方法研究证明有相当于试剂:钯=1:1及2:1的两种化合物生成。三、在乙醇溶液中,用0.001—0.005M 试剂溶液可以在大量其他金属存在下用光电悬浮滴定法测定3.3×10~(-5)M 到3.3×10~(-4)M 溶液中的钯。误差约在0至±3.5%左右(视干扰离子而定)。一次滴定需时二十分钟以内。 First, the masking of ethylenediaminetetraacetic acid disodium salt can avoid the interference of many cations on the determination of palladium with 5-iminothiazoline-2-thiocarboxamide. Second, the reagents and palladium generated by a variety of methods to prove that there is a reagent: palladium = 1: 1 and 2: 1 two compounds generated. Third, in the ethanol solution, 0.001-0.005M reagent solution can be used in a large number of other metals in the presence of a photoelectric suspension titration 3.3 × 10 ~ (-5) M to 3.3 × 10 ~ (-4) M solution of palladium . The error is about 0 to ± 3.5% (depending on interference ions). A titration takes less than twenty minutes.
