摘　　要：本文采用防腐高效溶样法,实验消解了国家标准物质GBW08517(海带)、GBW08571(贻贝)、GBW08573(黄鱼)、GBW010016(茶叶)、GBW07602(灌木枝叶)及GBW07603(灌木枝叶),标准模式测试了As、Cd、Cr、Cu、Hg、Mn、Pb、Se与Zn元素,测试结果大致与标准值相符合。该方法具有操作简单、扣合速度快(一秒扣合)、试剂用量少、密封效果好、安全可靠、消解完全(有效消解有机质)、批量处理(一次完成200个样品)等优点,可在生物及环境样品分析中广泛应用。Inductively coupled plasma mass spectrometry （ICP-MS） is common because of its unique capa- bility and has been widely used in geological, environmental, petroleum, chemical, food and life science fields. The pretreatment techniques are rapidly developed for ICP-MS. The more typical ways include open vessel dissolving sample way, conventional digestion way, microwave digestion way and higl~ pressure closed reaction vessel digestion way. This report describes that the determined values of As, Cd, Cr, Cu, Hg, Mn, Pb, Se and Zn at the same time in standard modes by ICP-MS were consistent with the certified values in reference materials such as GBW08517 （kelp）, GBW08571 （mussels）, GBW08573 （yellow fish）, GBW010016 （tea）, GBW07602 （shrub branches and leaves） and GBW07603 （shrub branches and leaves） using a high effective anticorrosion digestion way. The method has many advantages of easy operation, a- second capping, less reagents, difficulty to contamination, safety and reliability, good sealing, complete digestion （effective digestion organic matrix）, batch processing （once for 200 samples）, so it can be widely applied for biological and environmental samples.
