摘要
采用ICP-MS对选取的不同种类样品进行了测试,结果表明,首饰抛光灰中主要贵金属的含量取决于加工的饰品种类,并与抛光灰形态特征关系紧密。首饰抛光灰中,金的质量分数范围为0.47%-3.07%,铂的质量分数范围为0.216%-1.17%;两者质量分数和的范围为1.64%-4.07%。
Precious metals in different types of jewelry polishing ash samples are determined by ICP-MS.The testing results prove that the components of precious metals are decided by jewelry type,the shapes and characteristics of polishing ash.The mass fraction of gold in polishing ash ranges from 0.47% to 3.07%,that of platinum ranges from 0.216% to 1.17%,the sum mass fraction of both gold and platinum ranges from 1.64% to 4.07%.
