目的:建立电感耦合等离子体质谱(ICP-MS)测定酱腌菜中铅和总砷含量的方法。方法:样品在硝酸介质中经微波消解,消解液用ICP-MS同时测定酱腌菜中铅和总砷的含量。结果:ICP-MS 测定酱腌菜中铅和总砷标准曲线线性关系良好,相关系数分别为0.999和1.000;加样回收率分别为97.6%和108.3%,另利用10批市售样品与国标测定铅和总砷方法对比,相对偏差均小于20%,在误差允许范围内。结论:微波消解ICP-MS方法简便、快速、准确、可靠,适用于酱腌菜中铅和总砷的同时测定。
目的:建立電感耦閤等離子體質譜(ICP-MS)測定醬醃菜中鉛和總砷含量的方法。方法:樣品在硝痠介質中經微波消解,消解液用ICP-MS同時測定醬醃菜中鉛和總砷的含量。結果:ICP-MS 測定醬醃菜中鉛和總砷標準麯線線性關繫良好,相關繫數分彆為0.999和1.000;加樣迴收率分彆為97.6%和108.3%,另利用10批市售樣品與國標測定鉛和總砷方法對比,相對偏差均小于20%,在誤差允許範圍內。結論:微波消解ICP-MS方法簡便、快速、準確、可靠,適用于醬醃菜中鉛和總砷的同時測定。

Objective:To set up a method for simultaneous determination of lead,arsenic content in pickles by microwave digestion-inductively coupled plasma-mass spectrometry (ICP-MS).Methods:The pickles samples are digested in nitric acid solution with microwave digestion system,and the content of lead,arsenic in the digestion solution is determined simultaneously by ICP-MS.Results:The standard curve of ICP-MS determination of lead and total arsenic in pickles has a good linear relationship.The correlation coefficient is 0.999 and 1.000;the recoveries are 97.6% and 108.3%. This method has good linear relationship and high recovery.Then contrast with the national standard method for the determination of lead and total arsenic by using 10 batches of commercially available samples,the relative deviations are all less than 20%,in the range of allowable error.Conclusion:This method has simple operation,rapid analysis,high accuracy,and is reliable,and it can be applied for simultaneous determination of lead,arsenic content in pickles samples.
