活性炭吸附-原子吸收法测金在塔吉克斯坦金矿的应用

    The application of activated carbon adsorption-atomic absorption spectrometry in Tajikistan gold mine

    • 摘要: 采用活性炭吸附-原子吸收法对塔吉克斯坦库马尔克金矿样品进行测定,首先通过王水分离金矿样品,活性炭富集金,再将得到的金溶液提取定容,最后使用火焰原子吸收仪测定金的含量。该方法具有便捷快速、设备投资少、污染小等优点,笔者围绕该方法在塔吉克斯坦金矿实际中的运用展开具体的阐述。由实验结果可知,活性炭吸附-原子吸收法与泡塑吸附-原子吸收法测定结果的相对偏差均在允许相对偏差范围之内,外检样品的合格率达到95%以上,重复性和再现性好,完全适用于地质样品中金含量的测定。

       

      Abstract: Activated carbon adsorption-atomic absorption method was used for the determination of the Kumaerke gold mine in Tajikistan.By aquaregia, activated carbon riched gold, and then the gold solution was extracted and fixed volume, and finally the flame atomic absorption spectrometry determined gold content.This method has the advantages of convenient and fast, less investment in equipment and small pollution.The author elaborates on the practical application of this method in the gold mine in Tajikistan.The experimental results show that the relative deviation between the results of activated carbon adsorption-atomic absorption method and foam plastic adsorption atomic absorption spectrometry are within the allowable relative deviation range, and the passing rate of the external inspection samples is over 95%, and the repeatability and reproducibility are good.It is fully applicable to the determination of gold content in geological samples.
