title: [Determination of chloramphenicol in chloramphenicol and dexamethasone sodium phosphate ear drops by first derivative spectrometry].
abstract: Determination of chloramphenicol in the ear drops by first derivative spectrometry was studied. The detecting wavelength was 303.0 nm. The linear range was 0-65.2 micrograms.ml-1 (r = 0.9999). The average recovery was 99.84%, RSD = 0.37% (n = 8). The method is simple and accurate.
