The Total Arsenic Test of the Leaching Liquid of Arsenic-containing Waste by Hydride Generation-Atomic Fluorescence Spectrometry

Dai Jian-bo

Abstract

This method used intermittent flow injection and hydride generation-atomic fluorescence spectrometry to test the total arsenic content of the leaching liquid of arsenic-containing waste.Under the chosen test conditions,the linear equation of standard work curve: If=435.041×C+166.264(If is the fluorescence intensity,C is the arsenic concentration of the solution),of which the related coefficient is 0.9999.The DL is 0.005 μg/L,the accuracy is 2.6% and the recovery rate is 91.0%~105.0%.
