We report a facile method to determine total mercury in rain water by chemical vapor atomic fluorescence spectrometry and optimize the method conditions, which were carrier gas flow rate, Shielding gas flow rate, Hydrochloric acid concentration, Potassium borohydride concentration, etc. In the optimal conditions, the Correlation coefficient(r) was more than 0.998, detection limit is less than 0.0005ng/mL, and the recovery was from 93%.
