目前关于金的富集和测定方法很多,各有特色。为适应产金生产需要,本试验在前人的基础上把泡沫振荡吸附金,改为泡沫装柱动态吸附金,金的解脱采用热硫脲加双氧水加盐酸混合解脱液淋洗解脱,原子吸收测定。该法可使金在吸附过程中经许多次平衡,故吸附完全,同时扩大了吸附金容量,缩短了金分析周期,简化了操作程序,降低了成本。
At present there are many methods of enrichment and determination of gold, each with its own characteristics. In order to meet the needs of gold production, based on the previous experiments, the experiment was carried out by shaking the gold adsorbed on the foam to dynamically adsorb the gold by foam packing. The liberation of gold was liberated by the combination of thermal thiourea plus hydrogen peroxide plus hydrochloric acid mixed eluant, Determination. The method allows the gold in the adsorption process by many times the balance, so the adsorption is complete, while expanding the gold adsorption capacity, shortening the gold analysis cycle, simplifying the operating procedures and reduce costs.
