摘要: 采用微波消解-氢化物发生-原子荧光光谱法,对蘑菇中痕量硒进行了分析。利用阳离子交换法消除了阳离子的干扰。讨论并确定了实验的最佳测定条件,结果表明,硒的检出限为0.16ng/ml,回收率为96.2%~98.0%,相对标准偏差为1.6%。该法准确、快速、简便,应用于蘑菇中硒的测定,结果满意。

Abstract: It was is reported in this paper that the microwave digestion technique was used in the ion - exchange - separation hydride generation atomic fluorescence spectrometry determination of trace selenium in a-garic. The optimum conditions for the determination were tested and discussed. The detection limit was 0. 16ng/ ml. The recoveries of the method were 96. 2% ~ 98. 0% and RSD 1. 6% . This method was accurate, quick -acquired and convenient. It was used in the determination of trace selenium in agaric with satisfactory result.
