Abstract
En 中文
The accumulation of antibiotics in the environment and their increasing ecological risks make it essential to develop efficient and cost-effective technologies for treating refractory antibiotics-containing wastewater. Compared with conventional physical adsorption and biodegradation, electrochemical advanced oxidation processes (EAOPs) offer advantages including simple operation, free of additional chemicals, mild reaction conditions, and the ability to achieve both pollutant degradation and resource recovery. The carbon-based membrane shows great potential to be applied as a catalytic electrode, performing functions as conventional supports. This study fabricated self-supporting carbon nanofibrous membranes modified with phenolic resin (PR) by an electrospinning-thermal treatment strategy. The structural, conductivity, and mechanical properties of membranes prepared by four PR loading methods (immersion, spray coating, blend electrospinning, and grinding-remolding) were systematically studied. Owing to its superior conductivity and mechanical strength, the PR-I@PTA/ACFs-10 membrane prepared by the immersion method was selected as the working electrode in a flow-through electrocatalytic system for degrading tetracycline (TC). This configuration forces the reaction solution through the anode and cathode, significantly enhancing convective mass transfer and reactant contact. The results indicate that under conditions of 2.5 V, pH = 6, and 10 mM Na2SO4, the degradation rate of 10 mg L-1 TC reached 85.07% within 1 h. Through characterization techniques and DFT calculations revealed the synergistic mechanism of PR modification in promoting the generation of ·OH and optimizing electron transport pathways. The primary intermediates and potential degradation pathways were identified by LC-MS and DFT LUMO-HOMO calculations, providing deep insights into the complex transformation processes during TC degradation.
