中文摘要:
      采用电感耦合等离子体发射光谱仪(ICP-AES)测定铂含量的强度比值法(GB/T 21198.2-2007)是比较常用的方法,经过对该法的测试条件、标准溶液、强度积分面积优化后,对钯含量为80%、40%和20%的铂钯二元配方样品进行检测,探讨优化后的方法对钯含量较高的样品检测准确性。结果表明,优化后的方法,对于钯含量较高的铂钯合金,检测结果的稳定性和准确性较好,适用于高钯含量的铂钯配方首饰样品。
英文摘要:
      As an intensity ration method of testing platinum mass fraction, GB/T 21198.2-2007 is usually used for testing platinum mass fraction. Through optimizing the test condition, standard solution and intensity integral area, platinum-palladium alloy samples with palladium mass fraction of about 80%, 40% and 20% were detected using ion emission spectrometer (ICP-AES). Meanwhile, comparing our test results with design values and test data of other lab, the effect of the optimized method and the principle of the method were discussed in us paper. The results show that the stability and accuracy of the test results were better using the optimized method. Therefore, we can draw the conclusion that the optimized method is suitable for the platinum-palladium alloy jewelry samples with high palladium content.
