泡塑吸附原子吸收光谱法测定矿石中金的含量

Determination of gold in ore by bubble plastic absorption atomic absorption spectrometry

采用泡沫吸附原子吸收法对矿石中的金含量进行测定,不仅能够准确测定金的含量,而且方法简便、成本较低,在实际的矿产勘测中得到广泛应用。本文主要探讨了该试验原理、处理方法及相应测试条件,进而得出王水浓度及泡沫塑料形状等对试验结果的影响,在绘制曲线回归方程式后测定金的浓度在0~80ug/ml范围内线性关系良好,因此采用此方法对矿石中的含金量进行测定,可获得满意的结果。

The foam adsorption atomic absorption method for the determination of gold content in the ore can not only for the accurate determination of gold content, and the method is simple, the cost is low, in the actual mineral surveying and are widely used. Was mainly discussed in this paper. The test principle, processing method and the corresponding test conditions, and gets a conclusion that the effect of aqua regia concentration and foam shape on the test results, in drawing the curve regression equation after determination of gold concentration in good 0~80ug/ml linear relations of, so the use of this method for the determination of gold in ores, can obtain satisfactory results.
