Mass transfer and oxidant utilization are perhaps two of the most critical issues in sulfate radical (SO4•−) based advanced oxidation technologies (AOTs) their scaled-up implementation. In this study, we propose using hydrodynamic cavitation (HC), considered a green, effective method, to promote both mass zero-valent iron (Fe0) activated persulfate (PS) system. Whilst BET surface area Fe0 was increased by 8 times after HC treatment, concentration Fe2+ derived from is greatly for PS activation. The reappearance ensured good reusability catalyst. Likewise, impact pH revealed that TC adsorption on catalyst at acidic favored its degradation compared with higher pH. With respect utilization, it observed even high dosage (2.8 mM) completed converted within 30 min HC-Fe0/PS According SEM, TEM, analysis, conclude microjets induced bubbles or direct abrasion agitation have contributed removal hydroxide/oxide layers surface, thus reactivating catalytic activity. Given these reasons, up 97.80% Tetracycline (TC), model pollutant, synergistic coefficient as 2.62. After confirming SO4•− dominant reactive species, five pathways were proposed given intermediate evidence LC-MS/MS analysis density functional theory (DFT) calculations. Results study could provide new insights into role activation shed light potential implementation SO4•−-based AOTs wastewater treatments.

Abstract Engineered biochars are promising candidates in a wide range of environmental applications, including soil fertility improvement, contaminant immobilization, wastewater treatment and situ carbon sequestration. This review provides systematic classification these novel biochar composites identifies the future trends composite research application. It is proposed that metals, minerals, layered double hydroxides, carbonaceous nanomaterials microorganisms enhance performances via distinct mechanisms. In this review, four identified assessed critically. Firstly, facile synthesis methods, particular ball milling co‐pyrolysis, have emerged as popular fabrication strategies suitable for large‐scale applications. Secondly, modification with green materials, such natural clay minerals microorganisms, align well on‐going sustainable remediation (GSR) movement. Furthermore, new applications health improvement climate change mitigation support realization United Nation's Sustainable Development Goals (SDGs). Finally, importance field studies getting more attention, since evidence success critically needed before
