Summary: The solubility of mesalazine in ethylene glycol-water mixtures was studied at different temperatures, showing an increase with higher ethylene glycol mass fraction. The solubility also increased with temperature variations. Five solubility models were used to correlate experimental data and investigate accuracy. Additionally, apparent thermodynamic properties were calculated and discussed. Mesalazine was observed to be preferentially solvated by water and ethylene glycol in certain mixtures.

Summary: The persistence of recalcitrant pollutants in water is a major health issue. This study investigated the effect of phosphate on the degradation of atrazine by peroxydisulfate under visible light. The presence of phosphates was found to significantly decrease the efficiency of atrazine removal, due to the formation of less reactive phosphate radicals.

Summary: Porous carbon nano/microfibres modified by NiCoP nanoparticles were used as gas diffusion cathodes in a zero-gap alkaline water electrolyser. Two types of precursors, PAN and a combination of PAN and PVP, were used for the preparation of carbon fibres. The NiCoP/CF_PAN fibres, which were more porous yet stable, outperformed the NiCoP/CF_PAN-PVP cathode. Both cathodes showed high activity and exceptional stability under membrane alkaline water electrolysis conditions.

Summary: In this study, an active hydrogen evolution reaction (HER) catalyst was synthesized from MoNiO4 nano-rod arrays on nickel foam using high-temperature reductive annealing. The characterization of the nanostructure revealed the formation of a surface enriched polycrystalline MoO2 layer instead of a Ni4Mo alloy. The electrochemical dissolution of Mo and Ni was also investigated, with only Mo showing detectable dissolution phenomena, and the MoO2/Ni cathode prepared at 600 degrees C being the most stable. The catalyst exhibited stable hydrogen production in an anion exchange membrane water electrolysis (AEMWE) system for over 300 hours.

Summary: This study investigated the oxidation reaction of benzophenones, commonly used UV filters, by the oxidant potassium permanganate (KMnO4). The addition of potassium permanganate enhanced the reaction rate and efficiency. The degradation of benzophenones involved hydroxylation, bond breaking, polymerization, and carboxylation processes. Toxicity assessments revealed that the intermediate products formed during the degradation process posed a decreasing ecological risk.

Summary: The study demonstrates the effective degradation of the cyanotoxin CYN and its model compound 6-HOMU using ferrate(VI) oxidation. The uracil ring of CYN is oxidized and cleaved, leading to the generation of nontoxic cylindrospermopsic acid. This method shows promise for the treatment of CYN and uracil-based toxins in drinking water.

Summary: Low levels of natural organic matter (NOM) enhance removal of trimethoprim and sulfamethoxazole by ferrate(VI) through the formation of more reactive Fe(V) species. The presence of antibiotics in water sources threatens public health and ecosystems. Nine types of NOM and NOM model compounds were found to improve the removal of trimethoprim and sulfamethoxazole by ferrate(VI) under mild alkaline conditions, possibly due to the presence of phenolic moieties in NOMs. The formation of Fe(V) through single-electron transfer from NOM to Fe(VI) generates NOM radicals within milliseconds, resulting in the enhanced removal of antibiotics despite concurrent reactions between Fe(V) and NOM moieties, radicals, and water. Humic and fulvic acids from lake and river waters also showed similar results, supporting the enhanced abatement of antibiotics in real water situations.

Summary: Water is a crucial component of the United Nations' sustainable development goals, and water reuse is becoming increasingly accepted in response to global water scarcity. However, traditional treatment processes face challenges in treating low concentrations of pollutants in the presence of other chemicals. Advanced oxidation processes and the use of single atom catalysts offer promising solutions to these challenges.
