摘要:
目的 建立同时测定中药材枸杞子、百合、山药、菊花、山楂、薏苡仁中铬(Cr)、镍(Ni)、铜(Cu)、砷(As)、镉(Cd)5种元素的电感耦合等离子体质谱法(ICP-MS)。方法 采用微波消解法对枸杞子、百合、山药、菊花、山楂、薏苡仁药材样品进行前处理,以硒、锗、铟为内标,采用ICP-MS法同时测定样品中Cr、Ni、Cu、As、Cd的含量,并进行方法学考察。结果 检测的药材样品中Cr、Ni、Cu、As、Cd 5种重金属元素在0~50 μg·L-1低浓度范围内均有良好的线性关系(r≥0.999),重复性实验测定结果的相对标准偏差为1.46%~11.50%,加标回收率为84.43%~109.02%,与标准参考物质对照实验呈现良好的一致性。结论 建立的ICP-MS重金属检测方法操作简便,重现性好,结果准确,可用于中药材质量控制。
Abstract:
Objective To establish an inductively coupled plasma mass spectrometry (ICP-MS) for the simultaneous determination of five heavy metal elements of chromium (Cr),nickel (Ni),copper (Cu),arsenic (As) and cadmium (Cd) in Chinese medicinal materials of wolfberry,lily,yam,chrysanthemum,Chinese hawthorn and barberry.Methods The samples of wolfberry,lily,yam,chrysanthemum,Chinese hawthorn and barberry were pre-treated by microwave digestion method,and the contents of Cr,Ni,Cu,As and Cd in the samples were simultaneously determined by ICP-MS method with selenium,germanium and indium as internal standard.The methodological investigation was carried out.Results For the measured of five heavy metal elements of Cr,Ni,Cu,As and Cd,there was a good linear relationship (r≥0.999) in the concentration range of 0-50 μg·L-1,the relative standard deviation of the repeatable experimental measurement results was 1.46%-11.50%,and the spiked recovery was 84.43%-109.02%,and it was showed good consistency with the standard reference materials.Conclusion The established ICP-MS heavy metal detection method is simple,reproducible and accurate.It can be used for quality control of Chinese medicinal materials.
