Abstract:: ... Photodegradation is an important elimination process for many pharmaceuticals in surface waters. In this study, photodegradation of three antiviral drugs, acyclovir, zidovudine, and lamivudine, was investigated in pure water, freshwater, and seawater under the irradiation of simulated sunlight. Results showed that zidovudine was easily transformed via direct photolysis, while acyclovir and lamivud ...

Abstract:: ... The occurrence of sulfonamide antibiotics (SAs) in estuarine waters urges insights into their environmental fate for ecological risk assessment. Although many studies focused on the photochemical behavior of SAs, yet the effects of halide ions relevant to estuarine and marine environments on their photodegradation have been poorly understood. Here, we investigated the effects of halide ions on the ...

Abstract:: ... Photochemical transformation of hydroxylated polyhalodiphenyl ethers (HO-PXDEs) has attracted much attention for their ubiquitous presence and the photochemical formation of highly toxic dioxins. Dissolved organic matter (DOM) plays an important role in the environmental photochemical transformation of organic pollutants. However, the effects of DOM on the photolysis kinetics and dioxin formation ...

Abstract:: ... Electrochemical degradation of sunscreen agent benzophenone-3 (BP-3) and its metabolite 4-hydroxybenzophenone (4-OH-BP) was investigated by using a Ti/SnO2-Sb/Ce-PbO2 anode. Results showed that the degradation of BP-3 and 4-OH-BP followed pseudo-first-order kinetics, and the rate constants were 0.083 and 0.113 min−1 at a current density of 25 mA cm−2, respectively. The electrochemical degradation ...

Abstract:: ... Electrochemical degradation of trace antiretroviral drug stavudine was investigated by using a reactive electrochemical membrane (REM) with Ti/SnO2-Sb anode. From the results it was evident that the stavudine degradation followed pseudo-first-order kinetics, with the values of the degradation rate constant and half-life being 0.24 min−1 and 2.9 min, respectively, at a current density of 8 mA cm−2. ...
