Abstract: The determination of arsenic and mercury in agricultural soil by hydride generation atomic fluorescence spectrometry with using thiourea and ascorbic acid as reducing agent was introduced. The result showed that the correlation coefficient with calibration curve linearity of arsenic and mercury were 0.9997 and 0.9999 respectively. The detection limits of the method were0.010μg/g for arsenic, and 0.002μg/g for mercury, and the adding standard recovery was between 97.3% and 101.4%.
