Abstract:A method of simultaneous determination of phenol and aniline in waste water by absorbance ratio derivative is reported in this paper. The sample, with which the pretreatment steps such as extraction, distillation, color development, and acid addition were not needed, was directly determined by the proposed method. Several synthetic samples of phenol and aniline and some real samples of waste water were determined by the method and satisfactory results were obtained. Under the optimal experimental conditions, the linear ranges of determination are 1.01-24.24 mg·L-1 for phenol and 1.01-24.29 mg·L-1 for aniline. And the limits of detection are 0.097 mg·L-1 for phenol and 0.685 mg·L-1 for aniline. For synthetic mixtures, the relative standard derivations (RSD) are less than 2.60% for both phenol and aniline, and the recovery is in the range of 95%-104%, but for real water samples the recovery is in the range of 91%-108%. The proposed method features high sensitivity and rapid resolution.
