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 in hulless barley: iron, magnesium, calcium, manganese, and the pollution index of heavy metals: lead, cadmium, copper and zinc 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 sensitive, simple, rapid and accurate with pretreating and determining. This method has been applied to simultaneous determination of multi-trace elements in samples. The results will be satisfactory. The experiment data could provide an accurate and credible evidence for further exploitation of hulless barley.

Key words: inductively coupled plasma optical emission spectrometry (ICP-OES), hulless barley, trace elements
