Abstract:
A procedure for the enrichment of aromatic amines via solid- phase extraction was developed. A HR-P phase based on styrene- divinylbenzene was used for the investigations, generally followed by derivatization with iodine and determination via GC-ECD. The recoveries of 53 aromatic amines in a drinking water matrix at pH 9 were determined. Most anilines showed relative recoveries between 80-120% with relative standard deviations of less than or equal to 5% at concentration levels between 10 and 20 mu g l(-1). The comparison with a wastewater matrix led to similar results. The enrichment procedure was applied to real samples, e.g., samples of ammunition wastewater. (C) 1998 Elsevier Science B.V.
