Efficient Removal of Sulfamethoxazole in Electro-Oxidation System with Boron-Doped Diamond Anode and Electrolyte NaCl: Degradation Mechanisms

Molecules, Journal Year: 2025, Volume and Issue: 30(5), P. 1056 - 1056

Published: Feb. 25, 2025

In recent years, the pollutant sulfamethoxazole (SMX) that is widely used in medical therapy has been frequently detected different water systems. Thereby, it necessary to develop green and effective advanced oxidation strategies, especially electro-oxidation process. this study, an system featuring a boron-doped diamond (BDD) anode NaCl as supporting electrolyte was implemented effectively remove without addition of external oxidants. The operational parameters were optimized using response surface methodology with pH 7.5, current density 4.44 mA/cm2, concentration 20 mmol/L. optimization significantly enhanced degradation efficiency SMX obtain 100% removal 5 min. Results scavenging chemical probe experiments indicated presence hydroxyl radicals (•OH) chlorine (Cl•), latter primarily forming between reaction Cl- •OH. A competition experiment further revealed relative oxidative contribution Cl• 38.6%, highlighting its significant role Additionally, ion chromatography analysis confirmed formation harmful by-products such ClO4-, affirming environmentally friendly nature system. toxicity also assessed. application investigated explore influence coexistence ions well repeatability. Overall, work highlighted effectiveness for organic pollutants saline wastewater, demonstrating significance efficient sustainable environmental remediation.

Enhancement of aerobic denitrification process on antibiotics removal: Mechanism and efficiency: A review

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(3)

Published: March 1, 2025

Abstract Traditionally, the removal of nitrogenous pollutants from wastewater relied on conventional anaerobic denitrification as well aerobic nitrification and anoxic denitrification. However, is complicated since it requires stringent environmental conditions a large land, therefore, were performed in two separate reactors. Although high pollutant efficiency has been achieved via denitrification, demerits this approach include operational costs. Other traditional nitrogen methods air stripping, reverse osmosis, adsorption, ion exchange, chemical precipitation, advanced oxidation process, breakpoint chlorination. Traditional are not only but they also uneconomical due to Researchers have discovered that can be carried out by heterotrophic nitrification‐aerobic (HNAD) microorganisms which remove single reactor does require operating conditions. Despite significant effort researchers put in, there still little information known about mechanisms antibiotic during HNAD. This review begins with an update current state knowledge antibiotics The HNAD examined detail. Followed by, enhancement co‐metabolism sulfamethoxazole (SMX) response microbial communities toxicity. Lastly, favorable for biodegradation examined. findings show SMX main mechanisms, pathways proposed discussion. research indicated potential wastewater.

In this study, the biodiversity of endophytic bacteria cultivated grape varieties from vineyards Primorsky Krai, Russia, was analyzed for first time. Far Eastern with a high level stress resistance are unique object research as they in cold and humid climates short summer season. Grapevine microorganisms known promising agents biological control grapevine diseases agricultural pests. Using genomic approaches, we fungi most common Russia: Vitis vinifera × amurensis cv.
