摘要
用火焰原子吸收光谱法测定了矿石中的常量金。从高温焙烧温度、溶解样品系统、,泡沫预处理方法这三个方面,分析比较各种方法的优点和缺点。选择低污染,操作简单、快速、安全,成本低,应用范围广的最佳条件。
The constant gold in the ore is determined by flame atomic absorption spectrometry.The advantages and disadvantages of various methods are analyzed and compared from three aspects:the temperature of high temperature roasting,the dissolving sample system,and the foam pretreatment.Selection of low pollution,simple operation,fast,safe,low cost,the best application range of the best conditions.
