摘　　要：目的:建立电感耦合等离子体质谱法(ICP-MS)测定橡胶产品浸泡液中锌含量的方法。方法:橡胶产品浸泡液直接用ICP-MS进行测定,用内标法消除基体干扰。结果:本方法与分光光度法相比较,其结果差异无显著性(P>0.05);回收率在93.0%～99.5%之间,相对标准偏差2.59%。结论:可用ICP-MS测定橡胶产品浸泡液中的锌,方法准确﹑简便并且快速。Objective： To develop a method for determination of zinc in extraction liquor from rubber products by inductively coupled plasma mass spectrometry. Methods： The sample was directly determined by inductively cou- pled plasma mass spectrometry and internal standard method was used to correct matrix interference. Results： No significant difference was observed between ICP - MS and of national standard method （ P 0. 05） ,recoveries were 93. 0% ～ 99. 5% ; relative standaard deviation was 2. 59% . Conclusion： ICP - MS was suitable for determination of zinc in extraction liquor from rubber products with the advantages of accuracy,simpleness and rapidness.
