摘要
活性炭吸附—原子吸收光谱法、聚氨酯泡沫吸附—原子吸收光谱法和活性炭吸附—碘量法是常见的三种化验室测定低品位样品中金含量的方法。笔者通过长期的化验室工作对以上三种方法都进行了比较,结果发现聚氨酯泡沫吸附—原子吸收光谱法是一种能够有效控制误差并且污染最少的化验方法。
Activated carbon adsorption -AAS, polyurethane adsorption-AAS and activated carbon adsorption-iodine quantity method are common in the three laboratory determination of gold content in low grade samples. The above three methods are compared by writer through long-term laboratory work. The results show polyurethane loam adsorption-atomic absorption spectrometry is an effective control error and the least polluted assay method.
