微波消解-电感耦合等离子体质谱(ICP-MS)法测定刺三加药材重金属元素残留量
Microwave Digestion Inductively Coupled Plasma Mass Spectrometry(ICP-MS)Method for Determining Residual Heavy Metal Elements in Acanthopanax Trifoliatus Medicinal Herb
摘要
Abstract
Objective:To establish a method for determining the residual amounts of lead,arsenic,mercury,cadmium,and copper,five heavy metals in the traditional Chinese medicinal material of Acanthopanax trifoliatus,using microwave digestion combined with inductively coupled plasma mass spectrometry(ICP-MS).Method:After microwave digestion treatment of the samples,ICP-MS is used for determination under the Standard collision reaction cell mode.Results:The five heavy metal elements show good linearity within their respective ranges(R≥0.9992),with an average spiking recovery rate between 93.1％and 109.9％,and relative standard deviation(RSD)between 0.8％and 3.7％.In 11 batches of samples,the content of the five heavy metals do not exceed the limits of heavy metals and harmful elements stipulated in the 2020 edition of the Chinese Pharmacopoeia.Conclusion:The established method has the advantages of simple operation,high sensitivity,fast analysis speed,and high accuracy,and can be used for quality control of heavy metal elements in Acanthopanax trifoliatus.关键词
