在毛主席革命路线指引下,在文化大革命运动的推动下,我矿化验室经过反复试验,实现了湿法分析黄金。本法用王水溶样,以活性碳吸附柱分离金,并把旧法中过滤—吸附—过滤三步并作一步完成,最后用碘量法测定金。与火试金法相比,本法具有设备简单、操作容易、成本低、避免高温及铅中毒等优点,且准确度不亚于前法,分析速度亦比湿法中的氢醌滴定
Under the guidance of Chairman Mao’s revolutionary line and under the impetus of the Great Cultural Revolution, the mine laboratory has undergone repeated tests to realize the wet analysis of gold. This method is to use aqua regia to dissolve gold with activated charcoal adsorption column, and to filter-adsorb-filter three steps in the old method and complete it in one step. Finally, the gold content is determined by the iodometric method. Compared with the fire test method, this method has the advantages of simple equipment, easy operation, low cost, avoiding high temperature and lead poisoning, and the accuracy is no less than the former method, the analysis speed is also faster than the hydroquinone titration
