| Research Abstract |
Source water of drinking water was characterized with a comprehensive fractionation method. Hydrophilic and transphilic fractions were found to be major precursors of disinfection byproducts regardless the presence of nitrogen in the target disinfection byproducts, and basic fractions were minor contributors.
