Potassium permanganate–acridine yellow chemiluminescence system for the determination of fluvoxamine,isoniazid and ceftriaxone

Based on the oxidation of acridine yellow by permanganate in basic medium, a new chemiluminescence system was developed for the sensitive determination of some important drugs. The remarkable inhibiting effect of fluvoxamine, ceftriaxone and isoniazid on this reaction was applied to their detection. A possible mechanism was proposed for this system based on chemiluminescence emission wavelengths and experimental observations. Under optimum conditions, calibration graphs were obtained for 1 × 10^?9 to 1 × 10^?6 mol/L of fluvoxamine; 2 × 10^?8 to 8 × 10^?6 mol/L of ceftriaxone and 5 × 10^?8 to 4 × 10^?5 mol/L of isoniazid. This proposed method was satisfactorily used in the determination of these drugs in pharmaceutical samples and human urine and serum. Copyright © 2014 John Wiley & Sons, Ltd.
