建立了王水溶解纯金悪品、标准基体匹配、电感耦合等离子体发射光谱(ICP-AES)测定纯金饰品中痕量钯元素的定量分析方法。该方法具有简便、快速、灵敏度高、重现性好等优点。方法检出限为0.08μg/g，加标回收率为104%，相对标准偏差(RSD)为7.52%，A类不确定度为0.0119 mg/L。
The quantitative analysis method of trace palladium element in pure golden jewelry with inductively coupled plasma- atomic emission spectrometry (ICP-AES) was established. The samples were dissolved in aqua regia and Pd solution was matched with gold matrix. And then detected by ICP-AES. The test method proved better sensitivity,lower uncertainty and good accuracy, but also the test speed can be improved enormously. The analytical results showed that the detection limit of palladium trace element was 0.08 μg/g.The recovery rates of the studied elements was 104%.The relative standard deviations (RSD) of the method was 7.52%. The uncertainties of type A was 0.0119 mg/L.
