Development of Techniques and Methods for Determination of Haloacetic Acids in Drinking Water / 环境与健康杂志

ABSTRACT

Haloacetic acids are the main disinfection by-products in chlorinated drinking water,which are known or suspected to carcinogenic. Many countries have promulgated haloacetic acids as the routine monitoring item for drinking water safety. In order to better control the formation of haloacetic acids in chlorinated drinking water,many techniques and analysis methods were exploited. This review summarized the development of techniques and analysis methods and the comparative analysis was conducted in technique cost,method detection limit,sensitivity,resistance to disturb and sample pretreatment. The electrospray mass spectrometry is the best choice,but the instrument and operation cost is much higher,so the standard method based on the gas chromatography will still be the popular method for drinking water quality analysis.
