Special Issue Information

Dear Colleagues,

Oxidation catalysis is one of the major areas of interest for both academia and industrial chemistry. Besides playing a crucial role in the current chemical industry for the production of key intermediates such as alcohols, epoxides, aldehydes, ketones and organic acids, it will also certainly contribute to the establishment of novel green and sustainable chemical processes. Innovative systems for pollutant abatement and for the production of clean energy have been created based in advanced sustainable oxidative processes.

This special issue intends to outline the most recent achievements, current challenges and future opportunities on sustainable oxidative catalytic processes. The contribution of original research manuscripts or relevant critical review articles in this scientific field is both welcome and important for the current issue.

Abstract
The presence of estrogens and antibiotics in animal manure has raised considerable attention regarding their potential risks in both the soil system and human health. This study investigated the removal of estrogens (estriol (E3), bisphenol A (BPA), estradiol (17β-E2), ethinyl estradiol (EE2)), and [...] Read more.
The presence of estrogens and antibiotics in animal manure has raised considerable attention regarding their potential risks in both the soil system and human health. This study investigated the removal of estrogens (estriol (E3), bisphenol A (BPA), estradiol (17β-E2), ethinyl estradiol (EE2)), and antibiotic (sulfadimethoxine (SDM)) in livestock manure using the Fenton oxidation process. Based on the removal efficiency of estrogens and antibiotics, the optimal conditions of the Fenton oxidation process were as follows: an H2O2 dosage of 10.5 mmol/g slurry, an Fe2+/H2O2 molar ratio of 0.067 mol/mol, a stirring rate of 100 rpm, the feeding of an identical amount of H2O2 in two steps (at 0 and 15 min), a manure/reactor ratio of 1:25, and a reaction time of 100 min. Under these conditions, the removal efficiencies of E3, BPA, 17β-E2, EE2, and SDM in cow manure were 72.1%, 88.2%, 89.4%, 73.3%, and 99.7%, respectively. In the above-mentioned optimal conditions, the simultaneous removal of estrogens and antibiotic in different manure conditions led to the removal of above 70% of targeted contaminants, except for E3 in swine and chicken manure in all the manure. The findings demonstrate the useful application of the Fenton oxidation process in the concomitant removal of antibiotics and estrogens from animal manure, which reduces the associated risks to human health and environmental safety.

The availability of bound residues of polycyclic aromatic hydrocarbons (PAHs), in reference to their parent compounds, can be enhanced by microbial activity and chemical reactions, which pose severe risks for the ecosystems encompassing contaminated soils. Considerable attention has been raised on how to remove these bound residues from PAH-contaminated soils. This paper provides a novel application of Fenton oxidation in the removal of bound residues of model PAHs, such as naphthalene (NAP), acenaphthene (ACP), fluorene (FLU) and anthracene (ANT), from naturally contaminated soils. The citric acid-enhanced Fenton treatment resulted in the degradation of bound PAH residues that followed pseudo-first-order kinetics, with rate constants within 4.22 × 10−2, 1.25 × 10−1 and 2.72 × 10−1 h−1 for NAP, FLU, and ANT, respectively. The reactivity of bound PAH residues showed a correlation with their ionization potential (IP) values. Moreover, the degradation rate of bound PAH residues was significantly correlated with H2O2-Fe2+ ratio (m/m) and H2O2 concentrations. The highest removal efficiencies of bound PAH residues was up to 89.5% with the treatment of chelating agent oxalic acid, which was demonstrated to be superior to other acids, such as citric acid and hydrochloric acid. This study provides valuable insight into the feasibility of citric acid-Fenton and oxalic acid-Fenton treatments in rehabilitating bound PAH residues in contaminated soils. Full article
