Abstract: |
A novel chemiluminescence method for the determination of aceclofenac was developed,based on the fact that aceclofenac could enhance the chemiluminescence intensity from the reaction of potassium permanganate with formaldehyde in acidic medium.The experiments indicated that under optimum conditions,the enhanced intensity of chemiluminescence was linearly related to the concentration of aceclofenac in the range of 0.08-5.0 mg/L with a detection limit(3σ) of 3.0×10-2 mg/L.The relative standard deviation(RSD) was 1.7% for 0.50 mg/L aceclofenac solution in 11 repeated measurements.The method was successfully applied in the determination of aceclofenac in the tablets and capsules with recoveries of 981%-104.6%. |
