Disinfection of drinking water with chlorine-containing reagents leads to the formation of a large number of disinfection by-products resulting from the chlorination of natural dissolved organic matter. High-performance liquid chromatography/high-resolution mass spectrometry with preliminary solid-phase concentration on a polymeric sorbent was used to study the component composition of halogen-containing disinfection by-products in the tap water in Arkhangelsk. Fourteen chlorinated and brominated organic compounds belonging to classes of halophenols, aromatic acids and carbonyl compounds, chlorine-substituted nitrogen-containing heterocyclic compounds have been found. Based on the analysis of MS/MS spectra data, the possible structures of detected disinfection by-products are proposed.
