摘要
试样经王水分解、过滤、调节pH值、水合肼选择性还原后,采用重量法测定合金中金元素的含量,测定范围1%~90%。该方法具有回收率高,操作简单,重现性好等优点。
The test sample was dissolved with aqua regia, filtered, adjusted pH value, and reduced with hydrazine hydrate, the gold content in the alloy was measured by gravimetric method. The test range was 1%~90%. This method was simple with high recovery rate and good reproducibility.
