微波消解-火焰原子吸收分光光度法测定金的研究

Study on Determination of Gold in Ore by Microwave Digestion and Flame Atomic Absorption Spectrometry

研究了用微波消解矿石样品中的金,并用火焰原子吸收分光光度法对其进行测定的方法.结果表明,金含量在0～3.5 μg/mL范围内符合比耳定律,方法相对标准偏差在2.5%～3.2%之间,标准回收率在89%～104%之间,其结果令人满意.

The determination of gold in ore sample by Solid Phase Extraction and Flame Atomic Absorption Spectrometry was studied.The results show that the content of gold is compatible with the Beer law in the range 0～3.5 μg/mL;the relative standard deviations of the method are 2.5%～3.2%;and the recoveries are 89%～104%.
