Photocatalytic degradation and toxicity evaluation of diclofenac by nanotubular titanium dioxide–PES membrane in a static and continuous setup

摘要: Diclofenac is a commonly used anti-inflammatory drug, which has been found in surface waters. Advanced oxidation processes (AOPs) seem to be the most suitable technique prevent entry of diclofenac and other pollutants into TiO2 especially reliable mineralizing many organic molecules. The combination nanotubes with polymer microfiltration membrane (polyethersulfone, PES) showed high photocatalytic activity by degrading combined an excellent performance long-term stability. By continuously from water via cross-flow setup, molecules degraded are transported right so that overall reaction rate increased. toxicity was reduced photocatalysis photolysis; however, had greater impact. Moreover, complete degradation very important avoid highly toxic intermediate products.
