Application of the luminol chemiluminescence reaction for the determination of nine corticosteroids

A luminol chemiluminescence (CL) reaction was applied for the simultaneous determination of nine corticosteroids (triamcinolone, prednisolone, prednisone, cortisone, betamethasone, dexamethasone, corticosterone, flumethasone and triamcinolone acetonide) using flow injection. The luminol solution was prepared in NaOH with hexacyanoferrate(II) and hexacyanoferrate(III) was used as oxidant. Adequate isocratic chromatographic separation was obtained...
