黄原酯棉富集-火焰原子吸收法测定盐和水样中的痕量铅

Determination of Trace Pb in Salt and Water Samples by Flame AAS after Enrichment with Xanthate Cotton

本文介绍用黄原酯棉富集-火焰原子吸收法测定盐和水样中的痕量Pb,用于盐样中0.5—20μg/g和水样中5—200μg/L Pb的测定,结果与其它方法基本吻合。

A method is presented for determining trace Pb in salt and water samples by flame AAS after enrichment with xanthate cotton. The method is applied to determine 0.5-20 μg/g Pb in salt and 5-200 μg/L Pb in water. The results agree well with those obtained by other methods.
