摘要：

A novel chemiluminescence method was proposed for the determination of prulifloxacin. The method was based on the chemiluminescence reaction of the KMnO4-Na2S2O3-PUFX system sensitized by Tb3+. Under the optimum conditions, the chemiluminescence intensity was proportional to the concentration of the PUFX within the range of 5.0 x 10(-8) similar to 1.0 x 10(-5) mol L-1, and the detection limit was 8.0 x 10(-9) mol L-1. The proposed method was applied to the analysis of PUFX in tables, serum, and urine samples with satisfactory results. The possible mechanism of this sensitized CL reaction was also discussed.
