高量金的测定,一般经火法试金、活性炭或海绵吸附、离子交换、有机溶剂萃取富集分离后,分别选用重量法、氢醌滴定,碘容量法等测定。上述方法流程长,不能满足湿法冶金中间产品快速控制分析要求。孔雀绿比色快速测定低含量金,已有资料介绍,但用于高量金的测定,国内外未见报道。我们在资料的基础上通过试验,确定了孔雀绿差示分光光度测定的条件,建立了分析方法,在生产实践中,得到了好的效果。
Determination of high-volume gold, the general fire test gold, activated carbon or sponge adsorption, ion exchange, organic solvent extraction enrichment separation were selected gravimetric method, hydroquinone titration, iodine volume method such as determination. The above method has a long process flow and can not meet the requirements of rapid control analysis of intermediate hydrometallurgy products. Malachite green color fast determination of low levels of gold, information has been introduced, but for the determination of high amounts of gold, no reports at home and abroad. Based on the data we passed the test to determine the conditions of the malachite green differential spectrophotometry, the establishment of the analytical method, in the production practice, get good results.
