A method for the determination of phenol, chlorophenols and nitrophenols at levels below those allowed by international legislation in water from the public supply is proposed. Ten of the compounds studied are included on the USA Environmental Protection Agency priority list of aquatic pollutants. Samples are concentrated off-line on cross-linked polystyrene and subsequently subjected to capillary electrophoresis using the sample stacking procedure to remove the matrix. The recoveries afforded by the off-line concentration process and the behaviour of the phenols in relation to sample stacking injection were examined.
提出了一种测定公共供水水源水中苯酚、氯酚和硝基酚的方法，这些物质的含量低于国际法规允许的水平。所研究的化合物中有10种被列入美国环境保护局水生污染物优先清单。样品在交联聚苯乙烯上进行离线富集，随后采用样品堆积程序进行毛细管电泳以去除基质。考察了离线浓缩过程的回收率以及酚类在样品堆积进样方面的行为。
