摘要
用硝酸-氯酸钾溶样，氢化物发生-原子荧光光度法检测硫铁矿和硫精矿中砷含量，方法检出限0．2281ttg／L，加标回收率在90．1％-102．3％之间。该法为硫铁矿和硫精矿中砷含量提供了一个灵敏度高、方便快捷的新方法。
Arsenic in pyrites and concentrates was dissolved by nitric acid and perchloric acid , and detected by hydride generation - atomic fluorescence spectrometry. The detection limit of this method was 0. 2281μg/L,and the recovery for the sample was in the range 90.1% to 102.3%. This methed provided a new way of high - sensitivity, convenience and shortcut for determination of arsenic in pyrites and
