Role of Tertiary Amines in Enhancing Trihalomethane and Haloacetic Acid Formation During Chlorination of Aromatic Compounds and a Natural Organic Matter Extract

Tertiary amines are prevalent in waters due to anthropogenic inputs and are known to enhance organic compound degradation while increasing disinfection by-product (DBP) formation, via the strong chlorinating agent, R3N-Cl+. This study explored how tertiary amines can enhance trihalomethane (THM) and haloacetic acid (HAA) formation when various aromatic compounds (salicylic acid (SA), phenol (PHE) and resorcinol (RES)) and Suwannee River fulvic acid (SRFA) are chlorinated.
