Abstract

The influence of polysorb on the quantitative characteristics of stationary extraction for phenol and guayacol with mixtures of tributylphosphate (TBP) and organic solvents of different classes (distribution coefficients, synergecity) was studied. Solvation numbers and constants of entering of TBP into mixed solvates were calculated both for extraction and extraction-sorption systems. Comparative study of selectivity for a mixture of extracting agents has been made relative to phenol and guayacol in the extraction and extraction-sorption systems for variable composition of mixture of solvents. Separation of phenol and guayacol is possible when applying the columns with mixed stationary phases at the stage of the extraction sorption.
