摘要: The influence of suspended clay/solid particles on organic–coagulant reactions during water chlorination was investigated by analyses total product formation potential (TPFP) and disinfection by-product (DBP) distribution as a function exchanged clay cation, coagulant organic polymer, reaction time. Montmorillonite clays appeared to act catalytic center where the between adsorbed polymer disinfectant (chlorine) mediated closely cation. transition-metal cations in catalyzed more effectively than other chlorine, forming large number volatile DBPs. relative effects clays/solids followed order Ti-Mont > Fe-Mont Cu-Mont Mn-Mont Ca-Mont Na-Mont quartz talc. polymers TPFP follow nonionic anionic cationic polymer. role cation further confirmed observed inhibition DBP when strong chelating agents (o-phenanthroline ethylenediamine) were added suspension. Moreover, presence clays, DBPs increased appreciably either time or amount increased. For DBPs, halogenated methanes usually time-dependent, with chloroform dichloromethane showing greatest dependence.
