Determination of trace mercury in geochemical samples by cold vapor atomic fluorescence spectrometry

DU Shu-lan

Abstract

A method for trace mercury in geochemical samples by cold vapor generation—atomic fluorescence spectrometry.The experimental conditions that carrying gas flow amount,Aqua Regina concentration and KBH4 concentration etc.The detection limit of the method for mercury is 0.023ug/L,linear scope is 0-4.0 ug/L,precision is 1.1-5.0(RSD%) for mercury.This method is demonstrated accurate and reliable through testing of standard samples.
