Abstract
During water disinfection, due to the reaction between chlorine and natural
organic matter, mainly humic substances (HS), several non-desired halogenated
organic compounds, termed as disinfection by-products (DBPs), are formed. The
present paper presents the results obtained as part of a larger project. The
objective is to study the ability of certain spectrophotometric parameters, such as
ultraviolet absorbance (UV 254 nm) and fluorescence (exc. 320 nm; emiss. 435
nm), in controlling DBPs precursors during drinking water production.
The study has been carried out in a Spanish water treatment utility.
Concentrations of humic substances, total organic carbon (TOC), and two
spectrophotometric surrogates have been determined at different pl
