文章着重研究了铁离子对乙酸丁酯萃取火焰原子吸收法测定金的影响程度进行了探讨和分析,结果表明铁含量大于15%时,金测定值超出了测金允许的误差范围,严重影响了测金的准确性。
This paper focuses on the study of the influence of iron ion on the determination of gold by flame extraction with butyl acetate. The results show that when the content of iron is more than 15%, the value of gold exceeds the allowable error range of gold measurement, seriously affecting the Gold accuracy.
