本文主要研究了用甲基异丁基甲酮萃取原子吸收光谱法测定矿石中金元素含量的试验方法，探索了该方法的一些实验条件，经回收实验和精密度试验。统计分析表明：该方法测定结果准确可靠，准确度和精密度都较好。
In this paper, we mainly studied the method for the determination of gold content in ore by methyl isobutyl ketone extraction atomic absorption spectrometry. Some experimental conditions of the method were explored. The recovery experiment and precision test were carried out. Statistical analysis shows that the method is accurate and reliable, and the accuracy and precision are good.
