| 摘 要： | 本文报道采用ICP-AES法直接同时测定首饰金中合金无素及主要杂质元素含量,通过计算求得金含量。确定了仪器的最佳工作条件,进行了干扰试验。方法适用于18k～99.99%成色的首饰金。测定的RSD为<0.01%(对于高纯度金祥n=10)～0.2%(对于10k金样n=10)之间,分析结果表明,方法准确、快速、简便且样品消耗量少。

| Abstract: | This paper described a method of simultaneous and direct determination of alloy elements andmain impurity in jewelry by ICP--AES. Au content can be obtained by calculation. The inter-ferences of some elements were determined. The best analytical conditions have been found. Thismethod can be used in the analysis of 18k to 99.99% gold The relative standard deviatson isbetween 0.01% (n=10, for pure samples) and 0.20% (n=10, for 10K samples). This method isaccurate simple and rapid. Less amount of samples was consumed. |
