【摘要】 我们用高压溶样器做人体样品预处理,有效防止了样品消化过程中硒的挥发损失;用金电极阳极溶出伏安技术研究了人体中痕量硒的测定方法,确定了最佳测试条件,检出下限为2×10^-8g/L。实测人体样品,硒的回收率为96.6±6.7％（+SD）,变异系数CV为7.0％。更多还原

【Abstract】 We used High-pressure Wet Digester to pretreat the samples that were got from the human body. This method is very effective in preventing the selenium from undergoing volatilization that often occurs in the sample pretreatment,so the selenium loss is very little. We have studied the method of using anodic stripping vol-tammetry at gold-disc electrode to determine the trace selenium existing in the human body, where we found the best experimental condition for determining the trace selenium after a series of experiments. The detection limit is about 2×10-8g/L. Recovery of selenium is about 96.6±6.7% (X±SD), and the variant coefficient,CV=7.0%.更多还原
