Abstract
The suitable measurement conditions for the determination of cadmium in soil by hydride generation-atomic fluorescence spectrometry were investigated with thiourea as anti-interference agent and Co2+ as sensitivity enhancement agent.The detection limit of cadmium was 0.065 μg·L-1,and the linear of cadmium range was 0~20μg·L-1.The recovery was 95.0%~103.2%.The method had been successfully applied to the determination of cadmium in a series of national reference materials and the results were in good agreement with the certified values.
