Abstract

The use of modern chemical methods for the protection of aquatic ecosystems has become increasingly important. These methods are applied to remove toxic organic pollutants. This study presents a method for the remediation of water contaminated with toxic phenol using nanotechnology. The main objectives were: (1) to investigate the photochemical degradation of phenol by TiO2 nanoparticles in both nitrogen-doped and nitrogen-free systems; and (2) to determine the adsorption properties of rutile-phase TiO2 nanoparticles. Photochemical reactions were performed using TiO2 nanoparticles with sizes ranging from 10 to 32 nm, which were synthesized via the sol-gel method. The nanoparticles were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Additionally, the adsorption behavior of TiO2 nanoparticles was examined.
