Abstract
The use of a mixture (20:80, w/w) of keto-derivatized/underivatized po ly(styrene-divinylbenzene) copolymer for selective solid phase extract ion (SPE) of phenols in environmental water samples is described. Phen ols have been determined by liquid chromatography coupled with amperom etric detection. Experimental conditions for use of gradient in electr ochemical detection and comparison with other preconcentration techniq ues, such as on-line preconcentration and liquid-liquid extraction are also described. Different recoveries of phenolic compounds in environ mental samples according to the ratio of derivatized/underivatized cop olymer in SPE device are discussed.
