| Abstract: | An atomic fluorescence spectrometric method was developed to determine trace selenium in Chinese date by taking 10% HCl solution as the current-carrying solution, selecting 2.0% potassium borohydride solution to enhance fluorescence intensity, and eliminating the disturbance of Pb2+, Cu2+ and Ag+ by enrichment with mercapto cotton and masking with thioureaascorbic acid. Results showed that the linear range and detection limit were 1.0－32.0 ng/ml and 0.57 ng/ml, respectively; the recovery varied from 99.0% to 106.3% and the RSD was lower than 1.71%. |
