本文提出了一个测定矿石中微量银的新方法,在1.5mol/L的盐酸介质中,有碘化钾存在时(0.2％),银被二丁基卡必醇定量萃取,可在有机相直接火焰原子吸收测定银。
In this paper, a new method for the determination of trace silver in ore is proposed. In the presence of potassium iodide (0.2%) in 1.5 mol / L hydrochloric acid medium, the silver is quantitatively extracted by dibutyl carbitol, Absorb the silver.
