A procedure for the photometry determination of the phenol index of aqueous media is developed, which involves the preliminary separation of alkylphenols and their derivatives from water samples in sampling. Samples are filtered through an extraction chromatography column containing tributyl phosphate as an active component of the stationary phase followed by their quantification under the conditions of stepwise injection analysis. The detection limit of the method is 0.1 μg/L for simple phenol. © 2013 Pleiades Publishing, Ltd.
