摘要：
A novel flow injection chemiluminescence (CL) method for the determination of ciprofloxacin (CPLX) was reported. The proposed method is based on luminescence produced by KMnO4-Na2S2O4-Tb3+-CPLX chemiluminescence (CL) system. The effects of some critical experimental conditions were discussed and the optimization of working conditions was investigated. The linear dynamic range is 3.00 x 10(-8) similar to 9.00 x 10(-7) mol (.) L-1 and the detection limit for CPLX is 4.40 x 10(-9) mol(.)L(-1). This method was applied to the determination of CPLX in tablet, urine, and serum samples and the recoveries of real sample analyses were in the range from 110 +/- 4 to 104 +/- 4.
