原子吸收法测定水中痕量三价和五价锑

Determination of Trace Antimony(Ⅲ) and Antimony(Ⅴ) in Water With Atomic absorption

本文利用缝管原子捕集技术结合原子吸收法测定了水样中的锑(Ⅲ)和锑(Ⅴ),并研究了水样中Sb(Ⅲ)和Sb(Ⅴ)在APDC-MIBK体系中的萃取行为。锑的检出限为2.0μg/L,富集倍数可达100倍。 ‘。

We determinate truce antimony(Ⅲ) and antimony(Ⅴ) in water by atom trapping techniqe and atomic absorption. the extraction behaviour of Sb(Ⅲ) and Sb(Ⅴ) in water sample in APDC-MIBK has been investigated.The detection limit of sb is 2.0μg/ L, percon-centration factor of this method is 100.
