光谱法测定贵金属湿法冶炼物料中的金

Spectrometric method for the analysis of gold in hydrometallurgy materials of noble metals

将等离子体光谱法和X荧光光谱法应用于贵金属湿法冶炼物料中金的测定。通过对多种不同组成物料的测定及与经典火试金法进行的大量对照试验,拟定了测定金的新方法。光谱法具有测定快速、线性范围宽、准确度好、精密度高等优点,完全能满足生产控制及科研的需要。

Inductive coupled plasma emission spectrometry and Xray fluorescent spectrometry have been used to determine gold in hydrometallurgy materials of noble metals Many kinds of materials with gold were determined, and a large amount of tests compared with classical fire assaying method were carried out with satisfactory resultsThese two spectrometric methods have some advantages such as highspeed measurement,widelinear range,good accuracy and precisionThe methods can be applied to the determination of materials of production controlling and scientific research
