英文摘要	在酸性介质中,铁和钯分别与亚硝基r盐(nrS)络合形成绿色的fE-nrS和红色的Pd-nrS,利用一阶导数分光光度法在水相中同时测定fE和Pd.实验证明,两种络合物的摩尔吸光系数分别为1.94x10--4l·MOl--(-1)·CM--(-1)(对铁)和1.63x10--4l·MOl--(-1)·CM--(-1)(对钯);线性范围分别为0~5.6Mg/l(对铁)和0 ~7.0Mg/l(对钯);相对标准偏差均小于20%;回收率为96%~105%.本方法简便、快捷、准确、重现性好,适用于记忆合金电镀液及电镀层中fE和Pd的同时测定.; Fe and Pd can react with nitroso R salt (MRS) to form green Fe-NRS complex and red Pd-NRS complex individually in the acid medium.It can be determined in an aqueous phase by first derivative spectrophotometry directly.The molar absorptivities of the two complexes were found to be 1.94 × 104 L-mor-1·cm-1 for Fe and 1.63×104 L·mol-1-cm-1 for Pd.The linear ranges were 0 - 5.6 mg/L for Fe and 0-7.0 mg/L for Pd.The relative standard deviation was less than 2.0% , and the recovery was 96% -105%.The method is simple, rapid, reproducible and accurate.It has been applied to determine the Fe and Pd in the electroplating solution and electroplated layer of its alloy.
