【Abstract】 A fast and simple chemiluminescence(CL) method for the flow injection analysis of cefoperazone sodium is described based on its direct oxidation with potassium permanganate in acidic media. The CL can be enhanced by sodium dodecyl benzene sulfonate(SDBS) without any additional blank signal. The response of CL on concentration of cefoperazone sodium is linear in the range 0 01×10 -6 g/mL-15×10 -6 g/mL with a detection limit(3 σ ) of 3 9×10 -9 g/mL. Relative standard deviation (RSD) is 2 2% for 6.0×10 -6 g/mL cefoperazone sodium ( n =11). The proposed method has been successfully applied to the determination of cefoperazone sodium in the synthetical samples with satisfactory results.更多还原
