摘要
本研究建立了 ICP －MS 在线内标法测定葡萄酒中铁（Fe）、锌（Zn）、铜（Cu）、铬（Cr）、铅（Pb）、锡（Sn）6种重金属元素的方法，采用微波消解对6种元素的前处理方法及ICP－MS工作参数进行了优化。线性范围0～50μg／L 及0～5000μg／L，方法检出限均优于0．2μg／L，回收率在88．6％～109．8％，相对标准偏差RSD均小于6．0％。采用该方法对葡萄酒样品进行了分析，结果表明该方法能够满足重金属痕量检测需求。
An ICP-MS online internal calibration method for determination of heavy metals Fe、Zn、Cu、Cr、Pb and Sn in wine was established.Using the microwave digestion for the pretreatment method and the opera-tion parameters were optimized.The linear range were 0~50μg/L and 0~5000μg/L and the detection limit was lower than 0.2μg/L with recovery rate in 88.6%~109.8%,the relative standard deviation （n=6）less than 6%.Results of analysis of wine samples indicated that the method could meet the requirements of metal-lica’s trace analysis.
