Abstract
Abstract A novel chemiluminescence (CL) flow injection method for the determination of pazufloxacin mesylate (PZFX) is described. It is based on CL of a KMnO4–Na2S2O4 system sensitized by the complex [Eu(PZFX)2]3+, and shows the intensive characteristic bands of Eu3+. The optimum conditions for CL emission were investigated. Under the optimum experimental condition, the linear range is 1.0×10−8–1.0×10−6 mol/L and the detection limit is 2.6×10−9 mol/L. The method was successfully applied to the determination of PZFX in serum and urine samples. The possible mechanism for this CL system is discussed. The project was supported by National Natural Science Foundation of China (20331010) and Natural Science Foundation of Beijing (2022007).
