In this study, the impacts of three preoxidation strategies [i.e., using potassium permanganate (KMnO(4)), chlorine dioxide (ClO(2)), or hydrogen peroxide (H(2)O(2))] before preformed monochloramine (NH(2)Cl) addition on the formation and speciation of iodinated trihalomethanes (I-THMs) were evaluated at the Br(-)/I(-)
