摘　　要：旨在研究对比电感耦合等离子体发射光谱法(ICP法)以及原子吸收光谱法(AA法)两种方法在测定K金合金材料中镍释放量的测量结果。通过有针对性地选取市场上一些较为常见的K金合金材料样品,在模拟人工环境条件下,对选取的样品进行化学模拟实验,选用ICP法对其进行镍释放量的测定结果与采用国家标准GB/T 19719-2005《首饰镍释放量的测定光谱法》中推荐使用的AA检测方法试验结果进行对比,结果表明:采用ICP测量方法具有同等效果,一定程度上可以采用ICP法替代AA法进行K金合金中镍释放量的测定。The main purpose of this paper is to compare the measurement results of nickel release in K-gold alloy materials by ICP and AA. By selecting some common K-gold alloy materials in the market, under the condition of artificial environment,the chemical simulation experiment was carried out on the selected samples,and the results of the determination of nickel release by ICP method were compared with the results of the the AA test method recommended in the national standard GB/T 19719-2005 Jewellery-Determination of the release of nickel-Method of spectrometry experimental method.The results show that ICP method has the same effect.To some extent, ICP method can be used instead of AA method for the determination of nickel release in K-gold alloy.
