| 摘 要： | 采用HNO3-HClO4湿法消解对样品进行前处理,建立利用电感耦合等离子体发射光谱法(ICP-OES)对青稞中微量元素铁、镁、钙、锰及重金属污染指标铅、镉、铜、锌的含量进行测定的方法。结果显示,元素含量方法回收率在91.0%～106.3%之间,RSD小于3.3%,ICP-OES法具有灵敏、简便、快速、准确的特点,可同时进行多种微量元素的测定,结果较为理想,其测定结果可为青稞的进一步开发利用提供可靠的科学依据。

| Abstract: | Hulless barley was pretreated by wet digestion method(HNO3 and HCIO4),the trace elements iron,magnesium,calcium,manganese,and the pollution index of heavy metals lead,cadmium,copper and zinc in hulless barley were determined by ICP-OES.The results indicated that the recovery rate of the method were between 91.0% and 106.3%,with relative standard deviations of less than 3.3%.ICP-OES is a kind of sensitive,simple,rapid and accurate method which has been applied to simultaneous determination of multi-trace elements in samples with satisfactory results.The experiment data could provide an accurate and credible evidence for further exploitation of hulless barley. |
