| 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. |
