环境分析实验室管理样的含量估计及其应用

THE ESTIMATE OF CONTESTS OF THE MANAGEMENT SAMPLE IN THE LABORA- TORY OF ENVIRONMENTAL ANALYSIS AND ITS APPLYING

本文对自制管理样的定值及应用做了描述,样品采自新疆吐鲁番地区红、黄壤土,分析定值采用内检、外检方式,数据经统计检验处理,以多组均值求得总平均值作为元素的含量估计值,用±2S表示测量的单项不确定度.在土壤背景值研究等工作中应用的结果,各元素相对标准偏差(RSD)为:汞、镉大于 10％,铜、铅、锌、镍、氟均小于 10％。

The determinative value of the management ample made by oneself which from red and yellow soil in Turpan prefecture in Xinjiang had been analysed by means of the internal and external check and its applying was discussed. It is applied in the research on the soil background value, etc. The results show that RSD of the various element are Hg, Cd> 10%, Cu, Pb, Zn, Ni, F< 10%.
