Special Issue Information
Dear Colleagues,
Advanced oxidation processes (AOPs) are promising techniques, which can be used for various environmental applications. Currently, AOPs are receiving an extensive amount of interest from many researchers mainly due to their non-selective behavior and potential for pollutant oxidation, and lack of solid waste formation for the majority of them. However, there are some knowledge gaps in scientific literature, such as the efficiency and applicability of AOPs for real environmental water and/or wastewater matrices, effectiveness of AOPs for toxicity reduction, influence of environmental conditions and constituents on AOPs, cost of studied treatment methods, etc. This Special Issue invites original research papers as well as reviews focused on various environmental applications of AOPs, including but not limited to the following areas:
- Application of AOPs for removal of organic pollutants (e.g., CECs) from water matrices of diverse origin;
- AOPs for inactivation of microorganisms, e.g., viruses, bacteria, including those with antibiotic resistance, etc.;
- Application of AOPs for toxicity reduction;
- Life cycle assessment of AOPs;
- Operational conditions and economic assessment.

Abstract: Herein, we report a comparative study of photocatalytic (Xe-lamp 175 W) and sonocatalytic (345 kHz) degradation of EDTA and Rhodamine B (RhB) in the presence of Ti0 and [email protected] core-shell nanoparticles. [email protected] nanoparticles have been obtained by sonohydrothermal treatment (20 kHz, 200 °C) of commercially available Ti0 nanoparticles in pure water. The obtained material is composed of quasi-spherical Ti0 particles (20-80 nm) coated by 5-15 nm crystals of defect-free anatase. In contrast to pristine TiO2, the [email protected] nanoparticles extend the photo response from UV to NIR light region due to the light absorption by nonplasmonic Ti core. EDTA can be oxidized effectively by photocatalysis in the presence of [email protected] nanoparticles. By contrast, air passivated Ti0 nanoparticles was found to be inactive in the photocatalytic process for both EDTA and RhB. The efficiency of RhB photocatalytic degradation depends strongly on RhB concentration. At [RhB]≥ 1 10-3M, its photocatalytic degradation is not feasible. At lower concentrations, RhB photocatalytic degradation is observed but at lower efficiency compared to EDTA. On the other hand, we found that sonochemical degradation of RhB is quite rapid in a wide range of concentrations even in the absence of catalysts. For both, EDTA and Rhb, sonochemical and photocatalytic processes are more effective in the presence of Ar/O2compared with pure Ar. The obtained results suggest that the choice of the optimal method for organic pollutants degradation can be determined by their optical and complexing properties.
