文献应用了原子吸收光谱法测定硫化钠浸锑液中的微量金,我们将该方法应用于锑精矿中金的测定,效果良好。国内迄今测定锑矿中金的方法主要是火法。也有人做过光度法试验。但均步骤繁琐。用原子吸收光谱法直接测定锑矿中的金,常因样品中锑水解析出大量沉淀,使过滤困难并对金产生吸附而影响测定。本文在文献的基础上,在消除锑的干扰等方面做了工作。本法简便、选择性好。
The literature application of atomic absorption spectrometry for the determination of trace amounts of gold in the sodium sulfide leaching antimony solution, we apply this method to the determination of gold in antimony concentrates with good results. So far the determination of gold in antimony ore method is mainly the fire method. Some people have done photometric test. But all the steps are cumbersome. Direct determination of gold in antimony ore by atomic absorption spectrometry often results in the precipitation of large amounts of precipitates due to the hydrolysis of antimony in the sample, making the filtration difficult and affecting the determination of gold adsorption. Based on the literature, this paper has done some work in eliminating the interference of antimony. This law is simple, good selectivity.
