AbstractA simple, rapid and sensitive luminescence spectrometry is described for the determination of some beta- lactamic antibiotics in pure form and in pharmaceutical formulations. The proposed method is based on the fact that the redox reaction between cerium(IV) and beta-lactamic antibiotics in an acidic medium to form Ce(LII), which can luminesce, and sodium has great enhancement for the luminescence intensity of Ce(III). The method permits the determination of 8.0x10(-6)-2.0x10(-3)mg/ml, 1.0x10(-5)-2.0x10(-3)mg/ml, 2.0x10(-5)-2.5x10(-3)mg/ml, and 2.0x10(-5)-3.0x10(-3)mg/ml for cepharadine, cefalexin, 6-aminopenicillanic acid (6-APA) and cefazolin respectively. Their detection limits (S/N=3) were 2.0x10(-6)mg/ml, 7.0x10(-6)mg/ml, 6.0x10(-6)mg/ml, and 8.0x10(-6)mg/ml, respectively.
