摘要

利用仪器中子活化分析法研究了港湾沉积物ＳＲＭ１６４６中１３种元素（Ａｓ、Ｃｅ、Ｃｏ、Ｃｒ、Ｃｓ、Ｅｕ、Ｆｅ、Ｈｆ、Ｌａ、Ｒｂ、Ｓｃ、Ｓｍ和Ｔｈ）在５０μｇ至２０ｍｇ样品量范围内的分布均匀性，并计算了它们的取样常数。实验结果表明：元素分布的均匀度与元素本身的赋存状态及取样量有关。

Abstract

The distribution homogeneity of 13 elements（As

Sin and Th） in the esturine sediment SRM 1646 as evaluated by INAA in the range of sampling amounts from 50μg to 20mg.The sampling constants of these elements were also calculated.Our experimental results reveal that the homogeneity of the studied elements is related to their speciation and sampling amount.
