摘要
金催化剂采用王水分解定容后,经试验,取适量金催化剂溶液经活性炭分离富集、然后灼烧灰化,采用氢醌法滴定,对其已有的测量方法进行改进与讨论,建立了一套快速测定金催化剂中高含量金的方法。此方法快速准确,精密度在1.8%～3.39%,金的加标回收率在97%～102%。
Gold catalyzer was resolve by aqua regia, and then the amount of catayzer solution was added actived carbon. After separation, concentration and ashing, gold was titrated using hodroquinone standard solution. The method of measurement was improved and studied.A set of analysis methods for rapid determination of high-content gold in gold catalyst was established. The method is rapid and accurate. The degree of precision and addition recovery rate of this method is 1.8 %-3.39 % and 97 %-102 %, respectively.
