甲基异丁基戊酮萃取-AAS测定Au的改进

The Improvement of Determination of Au by AAS with MIBK Extract

利用MIBK在王水介质直接萃取Au,加入FeCl3消除基体差异,优化了仪器的条件及进行了标样的对照试验,对方法的可行性进行论证,通过改进而建立的快速有效,质量可靠的Au的分析方法。

Au in aqua regia was extracted directly by MIBK, FeCl3 was added to eliminate difference of the matrix. Instrumentation conditions were optimized. Compared the data to the standard,the method is faster and secure quality for the determination of Au.
