锰的准液膜富集及原子吸收法测定
Quasi Liquid Membrane Enrichment of Manganous ion in Environmental Sample and its Determination by Atomic Absorption Spectrometry
【摘要】 本文利用准液膜法与火焰原子吸收法相结合测定锰,方法的精密度为1.9%,回收率为98.9%,可富集测定ng/g级的锰。本方法已用于人发,湖水和茶中锰的分析。
【Abstract】 The method of determinat ion of trace manganous ion by using quasi liquid membrane and atomic absorption spectro photometry is described.The precision(RSD) and recovery are 1.9% and 98.9% respectively.Mn 2+ at ng/g level can be enriched.
