Ephedrine (EPH) is widely detected in the water environment, because it is the major ingredient in drugs treating influenza, asthma or hypotension, and is also a highly sought-after chemical precursor in the illicit manufacture of methamphetamine. In this study, transformation of EPH during the chlorination process was investigated for the first time, and the impact of water parameters including pH, different cations and anions on EPH transformation was evaluated as well. The degradation of EPH in the presence of NaClO fit the second order reaction kinetics, with a rate constant of 7...
