Abstract

For a simple and quick simultaneous determination of arsenic and antimony in soil,a soil sample was dissolved by using HNO 3 HCl(1+1) and the method of hydride generation atomic fluorescence spectrometry.The effects of the concentration of acid and reducing agent and interference from common coexisting elements on the determination of As and Sb were tested.The results read as follows:the recovery rates of arsenic and antimony are 95%～101% and 91%～93 8% respectively;the detection limits of arsenic and antimony are 0.36 and 0.41 μg/L.The results are in conformity with the standard value.
