This study investigated the photocatalytic degradation of codeine by UV-irradiated TiO2. The degradation kinetics was determined under varied conditions including the TiO2 loading, codeine concentration, and pH. Codeine and several reaction intermediates including morphine were identified and tracked during degradation using HPLC/MS–MS technique, along with TOC and IC measurements. Specifically, removal...
Methamphetamine (MAT) is a prescription drug and often a substance of abuse. It is found in WWTP influents and effluents as well as surface waters in many regions, elevating concerns about their potential impact. MAT is not effectively removed by conventional processes of domestic wastewater treatment plants (WWTPs). To contemplate advanced treatment, this study evaluates the feasibility of eliminating...
Photocatalytic degradation of atenolol (ATL) was investigated in aqueous suspensions using TiO 2 as photocatalyst. Complete degradation of 37.6μM ATL was obtained after 60min irradiation in pH 6.8 Milli-Q water in the presence of 2.0gL −1 Degussa P25 TiO 2 . Degradation of ATL followed pseudo-first-order reaction kinetics. Hydroxyl radical (HO) was determined to be the predominant...
