Abstract:

In this paper, a novel method fog determination of chemiluminescence (CL) spectra utilizing LS55 luminescence spectrophotometer was proposed. By this means, the CL spectra generated from the oxidation of cephalosporins with potassium permanganate was investigated. The result indicated that acid potassium permanganate CL system has more then three emitting species, excited state Mn(Ⅱ), Mn(Ⅲ) and singlet oxygen all could be assigned as the possible emitting species of this CL system. Base on above investigation results, sodium cefoperazone in pharmaceutical samples was determined by a CL analysis process combining with flow-injection technique. The detection limits estimated by a conservative model (3σ) of cefoperazone was 0.1µg dm-3, and the maximum relative standard deviation (RSD) was not more than 0.8 % (n=11, ρ=20µg dm-3).
