本文研究了在5～30％(v/v)王水介质中,金以氯化合物的形式定量吸附子一种新的螯合树脂上。当含金为1～30μg时通过一个简单的手续,就能与Cu(1.5g)、Fe(1.09)、Ni(100mg)、Pb(150mg)、Zn(40mg)等有效地分离。而吸附在整合树脂上的金能直接由热的硫脲(0.2％)—盐酸(1％)溶液进行解脱,解脱液定容后即可进行原子吸收测定。此法选择性好,简易快速。测定铜矿和铜精矿中0.05～x.0g/t品位的金,方法精密度和准确度好,对于0.x～0.0xg/t品位金其变异系数为1.6～2.2％。
In this paper, we studied the adsorption of gold on a new chelating resin as a chloride compound in 5-30% (v / v) aqueous aqua regia. It can be effectively separated from Cu (1.5g), Fe (1.09), Ni (100mg), Pb (150mg), Zn (40mg) and the like by a simple procedure when the gold content is 1 to 30μg. On the other hand, gold adsorbed on the integral resin can be released directly from the hot thiourea (0.2%) - hydrochloric acid (1%) solution. After the eluate is fixed, the atomic absorption spectrometry can be performed. This method is selective, easy and fast. The determination of gold in copper ore and copper concentrate of 0.05 ~ xg / t grade, the precision and accuracy of the method is good, for the 0.x ~ 0.0xg / t grade gold coefficient of variation of 1.6 to 2.2%.
