The correlation between the distribution coefficients of phenols in liquid extraction systems and extractive-chromatographs
systems with modified sorbents has been studied in order to investigate the influence of extractant characteristics on the
extractive activity of modified sorbent. We have used polysorb C processed with hexyl, heptyl and octyl alcohols, esters,
i.e., TBP, triisobytylphosphate and tricresylphosphate, aromatic carbohydrates, i.e., foluene and andoxylene.
