APPLICATION OF COMPOSITES PHOTOCATALYSTS FOR THE DEGRADATION OF P-NITROFENOL IN WATER


Abstract:

The environmental responsibility forces us to look for adequate ways to treat contaminated watewater by organic compounds and provide alternatives to the generator industries. Therefore, this work is based on the degradation of p-nitrophenol (PNF) applying tio composites on activated carbon (CA/TiO). The photocatalyst was supported on carbon powder (CA1) and carbon in flakes (CA2) which are called composites in order to recover it. the compounds were characterized with ir spectrum and electronic scanning microscope. the degradation of the pollutant was evaluated with a UV-visible spectrophotometer. A UV light (λ= 365 nm) was used to irradiate the reactor and H2O2 was used as an oxidizing agent throughout the whole process time. Once the different trials have been studied using a completely randomized experimental design, it was observed that the combina tion of CA1 shows a high efficiency (99.1 …
