Tetracycline has received a great deal of interest for the harmful effects substance abuse on ecosystems and humanity. The different processes degradation tetracycline were compared, with dual-frequency ultrasound (DFUS) in combination peroxymonosulfate (PMS) being most effective degradation. Free radical scavenging experiments showed that O2∙-, SO4∙- •OH main reactive radicals tetracycline. According to major intermediates identified, three possible pathways proposed, which are significance translational studies Notably, these found be significantly less toxicity. number active bubbles vessel was calculated using semi-empirical formula, higher value 1.44 × 108 L-1s−1 obtained when at 20 kHz (210 W/L) 80 (85.4 W/L). Therefore, compared kHz, although yield strong oxidizing substances from individual decreased slightly, significant increment still resulted synergistic effect, DFUS PMS should promoting generation free mass transfer within vessel, provides method efficient removal wastewater.

Facile synthesis of BiOI/BaNbO3 composite for rapid sonocatalytic degradation of tetracycline hydrochloride

Journal of Solid State Chemistry, Journal Year: 2024, Volume and Issue: 333, P. 124644 - 124644

Published: Feb. 27, 2024

Sonocatalysis, a vibration-induced chemical reaction, has shown great potential for catalytic applications. This study used water bath method to prepare BiOI/BaNbO3 composites with various mass ratios. Under the influence of sonocatalysis, BI/B-0.5 catalyst could degrade tetracycline hydrochloride up 96.5 % after 20 min, and stability was good. In comparison pure BiOI BaNbO3, reaction rate constants were found be 7.2 13.7 times higher, respectively. Furthermore, we systematically investigated sonocatalytic degradation effect on HTC under conditions. Finally, propose possible mechanism by composite catalyst. Our results underscore superior efficiency achieved catalyst, demonstrating its efficient removal organic pollutants.

Optimizing the UV-Fenton Degradation of m-Cresol Wastewater: An Experimental and Artificial Intelligence Modeling Approach

Industrial & Engineering Chemistry Research, Journal Year: 2024, Volume and Issue: 63(2), P. 921 - 929

Published: Jan. 6, 2024

Wastewater treatment, especially the efficient degradation of contaminants such as m-cresol, remains a pivotal challenge. This study investigates application artificial neural networks (ANN) in predicting total organic carbon (TOC) removal rates from m-cresol-contaminated wastewater by using ultraviolet (UV)-Fenton oxidation process. Six key variables, namely, Fe2+ dosage, H2O2 catalyst quantity, reaction time, pH, and substrate concentration, were employed inputs to ANN model. Leveraging this multivariable input comprehensive data set, model projected maximum TOC rate 87.12%, validated an efficiency 86.26% achieved through experiments under derived optimal conditions: dosage at 16.09 mg/L, 1.40 quantity 0.11 g/L, time 29.80 min, initial pH 3.66, concentration 50 mg/L. Comparative analysis with other machine learning algorithms further revealed that notably outperformed linear regression, support vector random forest terms precision. work paves way for resource-optimized experimental designs, fostering real-time monitoring refining advanced process proficiency industrial applications.
