The Role of Oxidative Treatment on the Trivalent Cation Complexation Properties of Natural Organic Matter
Keyword(s):
AbstractHumic acids (HA) which constitute the major subgroup of natural organic matter (NOM) are mainly composed of heterogeneous and polydisperse macromolecules. Considering the reactivities of the humic moieties towards the common coagulants during physico-chemical treatment of drinking water, different pre-oxidation conditions could exhibit various changes in humic acid structure leading to diverse reactivities towards the trivalent cations. The aim of this study was to evaluate the effects of the oxidative pre-treatment schemes applied by ozonation, TiO
