Abstract: | A sensitive and high selective chemiluminescence (CL) method was developed for the determination of lincomycin in acid medium using diperiodatonickelate as a reagent. The mechanism leading to luminescence is discussed by comparing the spectra of fluorescence and CL. Relative CL intensity is linear in the range from 8.0 ng mL?1 to 1.0 µg mL?1, the limit of detection is 2.5 ng mL?1 (3σ), and the relative standard deviation is 4.0% at 0.1 µg mL?1 of lincomycin (n?=?7). The method was successfully applied to the determination of lincomycin in injections, human urine, and in serum samples. |
