摘要：

The efficiency of ion chromatography columns packed with styrene-divinylbenzene copolymer containing quaternary ammonium groups to preconcentrate phenols at mu g l(-1) levels has been established. Retention is carried out in acidic medium based on non-polar interactions between the column and phenols. Pure acetonitrile was used for one step elution. Enrichment factors of at least 100 times are achieved. Regeneration of the column can easily be accomplished with a mixture of 60 mM nitric acid: methanol (1:99). Recoveries from a river water sample for nine priority pollutant phenols were in the range 92-105%. Other retained organic substances do not disturb liquid chromatographic determination of the phenols studied.
