Summary: The degradation of Metribuzin in aqueous solution was systematically investigated using Hydrodynamic Cavitation (HC) and HC combined with Hydrogen Peroxide (HC+H2O2). The combined HC+H2O2 process achieved a significant degradation of Metribuzin to the tune of 70.92%, with a TOC removal of 22%. Energy efficiency was compared between HC and HC+H2O2 treatment, demonstrating the efficient employment of HC coupled with H2O2 for Metribuzin degradation.

Summary: The interfacial properties and active site distribution of catalysts have a significant impact on catalytic oxidative desulfurization activity, which has been a research focus in recent years. In this study, an amphiphilic and polyoxometalate poly(ionic liquids) were prepared through cross-linking copolymerization and ion exchange reaction for desulfurization in fuel. The resulting sample, p-C2VIM-DVB-2-PMo, exhibited enhanced desulfurization performance and good thermal stability, meeting the requirements for deep desulfurization. Density functional theory calculations were also utilized to investigate the adsorption strength and interaction nature between the cation and sulfide compounds.

Summary: As a kind of AOPs, hydrodynamic cavitation (HC) is an energy-saving and easily scalable technology. Studying the degradation of dye molecules using HC is of great significance due to the toxicity, chroma, and difficult biodegradation of dyes. In this study, the HC treatment of methylene blue (MB) was investigated, and the effects of inlet pressure, solution pH, and initial concentration on MB degradation were explored. The results showed that introducing ozone had better degradation performance, and the reaction mechanism and path of MB were proposed based on the detection of intermediate products using LC-MS.

Summary: Decolorization of Ponceau 4R, Tartrazine, and Coomassie Brilliant Blue was studied using hybrid processes of hydrodynamic cavitation with potassium persulfate and hydrogen peroxide. The application of the dual oxidation system under cavitation conditions showed a synergetic effect, and the different decolorization values of the dyes could be explained by their different properties. The kinetic study revealed the highest first order rate constant for HC-KPS-H2O2, indicating the effectiveness of this combined process.

Summary: Nanobubble and ultrasonic cavitation were used to enhance oxidation reactions of ozonation, with nanobubbles increasing ozone dissolution by a factor of 16 and ultrasonic cavitation generating hydrogen peroxide. The process achieved significant improvements in both the loss of emitted ozone and radical recombination, demonstrated by the decomposition of rhodamine B. The combination of nanobubble and ultrasonic cavitation sustained oxidizing power by continuous dissolution of ozone and successive radical generation.
