摘要
目的 建立电感耦合等离子体质谱(ICP-MS)法同时测定僵蚕中钙、硼、钠三种元素含量的方法.方法 采用微波消解法作为前处理方法,采用ICP-MS测定 25批次僵蚕中钙、硼、钠三种元素含量并结合多元统计对不同产地僵蚕进行分析评价.结果 三种元素在各自范围内线性关系良好(r＞0.995);加样回收率在 80%～120%范围内;重复性RSD﹤5%;重现性RSD﹤5%;1D内稳定性RSD﹤5%.结论 该方法操作简单,结果准确,可用于僵蚕中三种元素的定量研究,结果可为僵蚕质量控制及产地研究提供参考.
Abstract
Objective A method was developed for the simultaneous determination of calcium,boron and sodium in Bombyx batryticatus by Inductively coupled plasma mass spectrometry(ICP-MS).Methods Microwave Digestion was used as the pretreatment method.The contents of Ca,B and Na in 25 batches of Bombyx batryticatus were determined by ICP-MS and analyzed by multivariate statistics.Results The three elements had a good linear relationship(r>0.995),the recoveries were in the range of 80%～120%,the reproducibility RSD<5%,the reproducibility RSD<5%and the stability RSD<5%within 1 day.Conclusion the method is simple and accurate,and can be used for the quantitative study of three elements in Bombyx batryticatus.The results can provide reference for the quality control and origin study of Bombyx batryticatus.
