Main Article Content

Abstract

The gas chromatography of spectrometry mass is one of the selected methods for analyzing trihalomethanes (THMs) in supplied water. Today, the combination of this method with the head-space technique (HS-GC-MS) has been found to have many advantages. It is a modern method for analyzing THMS in water without the solvent extraction step, which makes environmental pollution. The results showed the greatest sensitivity obtained in the following conditions: incubation temperature 52oC, incubation time 41 mins, NaCl concentration 3,5g/10ml. These optimal conditions are used to analyze THMS in some supplied water samples in Ho Chi Minh city.
