Rapid prediction of disinfection by-product formation potential by fluorescence

摘要

Recent drinking water regulations have lowered the disinfection by-product standards as well as added new disinfection by-products for regulation. Natural organic matter (NOM) plays a major role in the forma- tion of undesirable organic by-products following disin- fection/oxidation of drinking water. It is suspected that most precursors to disinfection by-products are humic, although nonhumic substances are also suspected of contributing to these by-products. Many of the disinfec- tion by-products have adverse health effects in humans (i.e., carcinogenic or mutagenic effects).
