摘要
文章简单介绍了火焰原子吸收背景产生的原因以及背景扣除的几种方法,并对利用非吸收线扣除背景测定矿石中低含量银的方法进行了探讨。本方法适用于矿石中银含量(2~100)×10-6样品的测定。
This article simply introduces the background of flame atomic absorption several reasons and background subtraction method, and use the non-absorption line of deducting background method of determination of low content of silver ore are discussed in this paper. This method is suitable for the determination of the mineral sample containing silver 2 ppm to 100 ppm.
