| Abstract: |
| In alkaline medium,gold nano particle could catalyze the chemiluminescence（CL)of the luminol-potassium permanganate system,and the presence of ceftazidime could enhance the CL intensity of this system.Based on this,a flow injection CL method for the determination of ceftazidime was established.Under the optimized conditions,the linear range for determination of ceftazidime was in the range of 30×10-5-50×10-2 g/L with a detection limit of 10×10-5 g/L.The relative standard deviation（RSD,n=11) was 20％ for 40×10-3 g/L ceftazidime.The method was applied in the determination of ceftazidime in injection with satisfactory results. |
