Trihalomethanes are main disinfection by-products of chlorination for drinking water. Their reaction mechanism is very complex, and most water plants have no ability to detect them. Mechanism of chlorination for natural organic matters (NOM) was studied by differential ultraviolet spectroscopy in this paper, and the experimental results suggested that chlorine mainly attacked the groups which have characteristic peak at about 266 nm, and all of differential UV spectroscopy under various chloridizing conditions showed identical change rules. Correlative analysis for lots of data indicated that there was a good relationship between trihalomethanes formation and ΔA₂₆₆, and a simple a predictive model of trihalomethanes formation was founded.
