Abstract

The determination of mercury in soil by atomic fluorescence spectrometry with hydride generation was studied.The relative factors of hydride generation atomic fluorescence for the determination were tested and discussed.The optimum conditions for the concentration of reducer and acid was developed.Under the optimum condition of instrument,the detection limit was 0.00108 mg·kg-1,the recovery of mercury was 109.2%～118.2%,and the relative standard deviation(RSD) was 5.48%.The method was simple,speediness and nicety,it was suit to determine quantities samples.
