Ultrasound-enhanced piezoelectric activation of Fe (Ⅵ) by ZnSnO3: A novel and efficient strategy for degrading sulfonamides antibiotics in unbuffered solutions
The environmental impact caused by the overuse of sulfonamide antibiotics is becoming increasingly severe, underscoring the urgent need for an effective and environmentally friendly solution. This study presents an innovative ZnSnO3/Fe (VI)/US system, which harnesses the piezoelectric properties of ZnSnO3, activated by ultrasound (US), to catalytically activate Fe (VI). In just 15 min, the system achieved an impressive degradation rate of over 95 % for SMT, far surpassing the performance of individual systems. Even after six cycles, the degradation efficiency remained above 85 %. The synergistic mechanism of ultrasound and ZnSnO3 in activating Fe (VI) was thoroughly investigated, revealing how ultrasound-induced polarization in ZnSnO3 facilitates electron transfer to Fe (VI), reducing it to reactive Fe (V) and Fe (IV) species that drive pollutant degradation. This new approach provides a novel, eco-friendly solution for sulfonamide removal. Moreover, the system operates in ultrapure water, eliminating the need for buffered solutions traditionally required in Fe (VI) activation, offering a groundbreaking strategy for Fe (VI) activation in environmental remediation.
期刊介绍:
The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
