摘要
本文用ＴｒｉｔｏｎＸ－１００－氯化铵为干扰抑制剂研究了测定钢铁中铬的工作条件。该法可消除大量铁和其他共存元素的干扰。提高了灵敏度。浓度直线范围为０～４０μｇ／ｍＬ，相对标准偏差为１．５％～３．６％。本方法快速、简便、测定结果准确。
In this paper,The determination ofChromium in steel by AAS using TritonX-100 and Ammondium Chloride as interfer-ence suppressor has been stuided. The inter-ferences of iron and other exist elements aresupressed efficiently. and the sensitivity fordetermination of Chromium is increased. Thelinear range is 0～40μg/mL and its coeffi-cients of variation are between of 1.5%～3.6%. This method is convenient,rapid and accurate.
