The removal of synthetic musks and several other personal care product chemicals from wastewater by reaction with oxidizing and reducing radicals was investigated. The kinetics of these radical reactions were observed to determine the second order rate constants. Competition kinetics were performed for the hydroxyl radical reactions using KSCN and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) as standards, while direct observation of the sulfate radical and hydrated electron reactivity was possible. In total, twenty-eight rate constants for 10 different compounds were determined. Additionally, some structure-activity relationships for these radical reactions are proposed. Finally, a relative rates analysis was performed to determine the possible efficiency of the removal of these chemicals in real-world waters.
