Abstract

Analytical methods for haloacetonitriles and chloral hydrate in tap water by extraction and detection by GC-ECD, GC/MS and GC-NPD methods were studied.
Good results were obtained by using GC/NPD method for the analysis of haloacetonitriles and by using GC/MS method for the analysis of chloral hydrate.
The result indicated that dichloroacetonitrile and chloral hydrate were volatilized like trihalomethane by heating.
