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.

Herein, we report a comparative study of photocatalytic (Xe-lamp) and sonocatalytic (345 kHz power ultrasound) degradation of Ethylenediaminetetraacetic acid (EDTA) and Rhodamine B (RhB) in the presence of Ti0 and [email protected]2 core-shell nanoparticles (NPs). [email protected]2 NPs have been obtained by sonohydrothermal treatment (20 kHz, 200 °C) of commercially available Ti0 NPs in pure water. The obtained material is composed of quasi-spherical Ti0 particles (30–150 nm) coated by 5–15 nm crystals of anatase. In contrast to pristine TiO2, the [email protected]2 NPs exhibit the extend 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]2 NPs. By contrast, air passivated Ti0 nanoparticles was found to be inactive in the photocatalytic process for both EDTA and RhB. Photocatalytic degradation of EDTA over [email protected]2 NPs exhibits strong photothermal effect, which has been attributed to the higher yield of oxidizing radicals produced by light at higher bulk temperature. The efficiency of RhB photocatalytic degradation depends strongly on RhB concentration. At [RhB] ≥ 1 × 10−3 M, its photocatalytic degradation is not feasible due to a strong self-absorption. At lower concentrations, RhB photocatalytic degradation is observed, but at lower efficiency compared to EDTA. We found that the efficient sonochemical degradation of RhB does not require the presence of any catalysts. For both processes, EDTA and RhB, sonochemical and photocatalytic processes are more effective in the presence of Ar/O2 gas mixture compared to pure Ar. The obtained results suggest that the choice of the optimal technology for organic pollutants degradation can be determined by their optical and complexing properties. Full article

Photo-induced Advanced Oxidation Processes (AOPs) using H2O2 or S2O82− as radical precursors were assessed for the abatement of six different contaminants of emerging concern (CECs). In order to increase the efficiency of these AOPs at a wider pH range, the catechol organic functional compound was studied as a potential assistant in photo-driven iron-based processes. Different salinity regimes were also studied (in terms of Cl concentration), namely low salt water (1 g·L−1) or a salt–water (30 g·L−1) matrix. Results obtained revealed that the presence of catechol could efficiently assist the photo-Fenton system and partly promote the photo-induced S2O82− system, which was highly dependent on salinity. Regarding the behavior of individual CECs, the photo-Fenton reaction was able to enhance the degradation of all six CECs, meanwhile the S2O82−-based process showed a moderate enhancement for acetaminophen, amoxicillin or clofibric acid. Finally, a response-surface methodology was employed to determine the effect of pH and catechol concentration on the different photo-driven processes. Catechol was removed during the degradation process. According to the results obtained, the presence of catechol in organic macromolecules can bring some advantages in water treatment for either freshwater (wastewater) or seawater (maritime or aquaculture industry).

The petroleum industry is one of the most rapidly developing industries and is projected to grow faster in the coming years. The recent environmental activities and global requirements for cleaner methods are pushing the petroleum refining industries for the use of green techniques and industrial wastewater treatment. Petroleum industry wastewater contains a broad diversity of contaminants such as petroleum hydrocarbons, oil and grease, phenol, ammonia, sulfides, and other organic composites, etc. All of these compounds within discharged water from the petroleum industry exist in an extremely complicated form, which is unsafe for the environment. Conventional treatment systems treating refinery wastewater have shown major drawbacks including low efficiency, high capital and operating cost, and sensitivity to low biodegradability and toxicity. The advanced oxidation process (AOP) method is one of the methods applied for petroleum refinery wastewater treatment. The objective of this work is to review the current application of AOP technologies in the treatment of petroleum industry wastewater. The petroleum wastewater treatment using AOP methods includes Fenton and photo-Fenton, H2O2/UV, photocatalysis, ozonation, and biological processes. This review reports that the treatment efficiencies strongly depend on the chosen AOP type, the physical and chemical properties of target contaminants, and the operating conditions. It is reported that other mechanisms, as well as hydroxyl radical oxidation, might occur throughout the AOP treatment and donate to the decrease in target contaminants. Mainly, the recent advances in the AOP treatment of petroleum wastewater are discussed. Moreover, the review identifies scientific literature on knowledge gaps, and future research ways are provided to assess the effects of these technologies in the treatment of petroleum wastewater.

The application of Fenton-based advanced oxidation processes (AOPs), such as photo-Fenton or electro-Fenton for wastewater treatment have been extensively studied in recent decades due to its high efficiency for the decomposition of persistent organic pollutants. Usually Fenton-based AOPs are used for the degradation of targeted pollutant or group of pollutants, which often leads to the formation of toxic by-products possessing a potential environmental risk. In this work, we have collected and reviewed recent findings regarding the feasibility of Fenton-based AOPs (photo-Fenton, UVC/H2O2, electro-Fenton and galvanic Fenton) for the detoxification of real municipal and industrial wastewaters. More specifically, operational conditions, relevance and suitability of different bioassays for the toxicity assessment of various wastewater types, cost estimation, all of which compose current challenges for the application of these AOPs for real wastewater detoxification are discussed.

Title: Photocatalytic and sonocatalytic degradation of EDTA and Rhodamine B over Ti0 and [email protected] nanoparticles

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.
