泡沫吸附法中灰化法与硫脲解脱法测定矿石中金的比对

Determination of gold in ore by ashing method and thiourea relief mothod of foam adsorption method

目前,想要测定矿石中的金的含量有很多方法,一般实验室采用火焰原子吸收、泡沫塑料富集、硫脲解脱等等。经试验研究,我们发现泡沫塑料吸附法实用更广泛。本文主要探究一下矿石中金的泡沫吸附法中灰化法与硫脲解脱法对比。结表明灰化法要优于硫脲解脱法。

At present, there are a lot of methods to determination of gold in ores. In laboratory, we generally adopt flame atomic absorption, foam enrichment and thiourea relief etc. Though the experimental study, we found that the foam adsorption method applied more widely. In this paper, ashing method and thiourea relief method of foam adsorption are contrasted. The results show that, the ashing method is better than the thiourea relief method.
