电感耦合等离子体发射光谱法分析青稞中微量元素的研究OA北大核心CSCDCSTPCD
Analysis of Trace Elements in Hulless Barley by ICP-OES
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.
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 …查看全部>>
