Abstract

A rapid, sensitive and selective method has been developed for the determination of palladium with 5,6-dimethyl-1,3-indanedione-2-oxime in acetate buffer (pH 5.5). Beer's law is obeyed over the range 0.15-4.17 mug/ml palladium(II). The molar absorptivity at 370 nm is 2.98 x 10(4) 1.mole(-1).cm(-1). The method has been applied for the determination of palladium in synthetic mixtures corresponding to PtIr and Oakay alloys. An interesting feature of the system is the abnormal shape of the Job and molar-ratio plots obtained.

摘要

已开发出一种快速、灵敏且具有选择性的方法，用于在乙酸盐缓冲液（pH 5.5）中用5,6-二甲基-1,3-茚满二酮-2-肟测定钯。钯（II）浓度在0.15 - 4.17微克/毫升范围内遵守比尔定律。370纳米处的摩尔吸光系数为2.98×10⁴升·摩尔⁻¹·厘米⁻¹。该方法已应用于测定对应于铂铱合金和奥凯合金的合成混合物中的钯。该体系一个有趣的特点是所得到的乔布曲线和摩尔比曲线形状异常。
