[Text] / V. V. Sursyakova, G. V. Burmakina, A. I. Rubaylo // J. Anal. Chem. - 2015. - Vol. 70, Is. 1. - P98-105, DOI 10.1134/S1061934814110124. - Cited References: 39 . - ISSN 1061-9348. - ISSN 1608-3199

Аннотация: The conditions of the sorption preconcentration of phenols from samples of natural and potable waters in Diapak P concentrator cartridges filled with super-cross-linked polystyrene are optimized. Countercurrent desorption with acetonitrile or methanol ensures the elimination the step of organic solvent evaporation. The observed reduction of the sorption of humic and fulvic acids (HFA) on the addition of sodium sulfite to the samples of natural and potable waters prior to their processing probably relates to the change of pH. The preconcentration of phenols from natural and potable waters at pH 6-8 substantially reduces the sorption of HFA. The method is used to determine phenols in samples of tap water and water from the Yenisei river by the added-found method.

Аннотация: The present work is, an attempt to present a critical review of the data on which infra-red spectral correlations are based, indicating the classes of compounds which have been studied in each case and the known factors which can influence the frequencies or intensities of the characteristic bands. Especial attention has been paid to paublications dealing with the groups of compounds containing common structural units and although a considerable number of fundamental studies on single molecules have been covered
