In this paper we report a method based on solid-phase extraction (SPE) and subsequentanalysis by gas chromatography combined with mass spectrometry for determination ofchloroform in potable water. The affinity of chloroform for the resin enables almost completerecovery of the analyte. The analytical method proposed enables evaluation of chloroformlevels down to 0.295 lg L)1. The procedure is characterized by lack of interferences, in fact theGC–MS analysis reveals the presence of only one peak, that of chloroform. Use of CDCl3 aslabelled internal standard also makes the procedure suitable for use as a reference analyticalmethod for quantification of chloroform in drinking water.

Abstract
In this paper we report a method based on solid-phase extraction (SPE) and subsequentanalysis by gas chromatography combined with mass spectrometry for determination ofchloroform in potable water. The affinity of chloroform for the resin enables almost completerecovery of the analyte. The analytical method proposed enables evaluation of chloroformlevels down to 0.295 lg L)1. The procedure is characterized by lack of interferences, in fact theGC–MS analysis reveals the presence of only one peak, that of chloroform. Use of CDCl3 aslabelled internal standard also makes the procedure suitable for use as a reference analyticalmethod for quantification of chloroform in drinking water.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
