双硫腙-棉花柱富集分离水中痕量铅的条件研究

Research of Conditions of Trace Plumbum Pre Concentration from Water on a Cylinder of Cotton Using Dithizone as a cheating Agent

本文研究了用双硫腙浸泡过的棉花来富集、分离水中痕量铅的适宜条件。讨论了几种金属离子对铅测试的影响。

In this paper the optimized conditions of enriching trace plumbum in water on a cylinder of dithizone cotton are researched.The interference of several metal ions was discussed.The recoveries of plumbum were determined in different enrichment conditions by flame atomic absorption spectrometry(FAAS).
