摘要
通过综合对比实验,从多种样品预处理方法中筛选出测定大气颗粒物中金属含量的样品预处理方法——HNO_3-HClO_4热消解提取法。该法操作简便、易于掌握,待测金属及其化合物提取率达90％以上(滤筒样品84％以上),而且空白值低,可与化学法及仪器法配套使用。
The pretreatment system (HNO3-HC1O4) for the determination of metals in the atmospheric particle was established based on other experiments in the study. The system is easy to operate and hold. The lixiviate rate of the metals and their compounds needing to determine was over 90%. Moreover, the vacant value is lower. It is an auspice for the chemical analysis and instrumental analysis.
