摘　　要： 研究了司帕沙星-铕体系的荧光光谱特性,在体系的最大激发波长(322nm)和最大发射波长(616nm)下,确定了铕的最佳浓度和体系的pH值。在最佳条件下,司帕沙星浓度在2～10mg/L的范围内与体系的荧光强度呈线性关系,检测限为0.08mg/L。对样品进行加标回收试验,回收率为96.5%～102.0%,RSD为2.5%～3.1%。利用该法测定了司帕沙星片剂中的司帕沙星含量。 The fluorescence characteristics of the system SPLX - Eu was reported. At the optimum excitation wavelength （322 nm） and emission wavelength （616 nm）, the concentration of Eu, and pH were determined. Under the optimum conditions, the linear range was 2.0 - 10 mg/L for SPLX, and the detection limit was 0.08 mg/L. The proposed method was applied to the determination of sparfloxacin in tablets with satisfactory results. The average recovery was in the range of 96.5% - 102.0% and the RSD was 2.5% -3.1%.
