摘要
本文讨论了铁基体对多种元素的光谱干扰情况，采取选择谱线、峰切除、基体匹配等手段，有效地消除了铁 基体的干扰。应用于净水剂三氯化铁中十一种元素的测定，其方法的精密度（ＲＳＤ％）在０．９６～４．１０（ｎ＝１０），样品 加标回收率在８９．５％～１２５．８％，其准确度、精密度能满足分析要求。
In this paper, spectral interference of iron matrix with 11 kinds of elements was discussed. With spectral line selected, peak cut off, matrix matched, the interference of iron has been effectively eliminated. The RSD% of this method was between 0. 96 and 4. 10%. The recoveries of practical samples were 89. 5%~125. 8%. The method was applied to the analyse of water treatment agents with satisfactory results.
