Abstract:

Antidepressants are an important part of pharmaceutical contaminants that are new pollutants becoming potential threat to the environment. The existing sewage treatment techniques can hardly treat them effectively. This study focuses on the application of electron beam irradiation to degradation of antidepressant amitriptyline (AMI). The influencing factors include initial concentration, irradiation dose, pH, amount of H$_{2}$O$_{2}$, various atmosphere conditions and different ions. The degradation behavior of AMI in real water environment was simulated, and possible degradation paths were proposed according to the product analysis. The above mentioned factors have shown important influences on the irradiation degradation of AMI. Degradation of target AMI obeyed the pseudo first-order kinetic equation. When the dose of irradiation was 5 kGy, the target pollutant was completely degraded, meaning that electron beam irradiation is an effective means to treat wastewater containing AMI.

Key words: antidepressant, amitriptyline, electron beam irradiation, degradation
