Green-Activated Charcoal-Anchored Iron Oxide-Driven Microbial Electro-Fenton System for Sustainable Mitigation of Refractory Contaminants

ACS ES&T Water, Journal Year: 2024, Volume and Issue: 4(9), P. 4129 - 4139

Published: Aug. 1, 2024

The contamination of natural water bodies with dyes and other refractory compounds is a menacing issue in developing nations. Despite stringent laws, industrial effluent not managed efficiently, as it incurs additional cost. Hence, the present research focuses on sustainable mitigation contaminants using self-driven bioelectro-Fenton (BEF) system. iron-activated charcoal (Gt-Fe/AC) cathode-cum-Fenton catalyst used this investigation was synthesized waste green tea extract biogenic agent. catalyst-driven BEF system (Gt-Fe/AC-MFC) achieved maximum power density 111.7 ± 3.1 mW/m2 operating voltage 108 3 mV, while parallelly degrading 20 mg/L Coomassie Brilliant Blue (CBB) dye almost entirely 300 min at neutral pH. Additionally, high removal Congo red (96.8 1.2%) methylparaben (90.9 0.6%) attained under similar conditions. Moreover, Fe-AC-catalyzed performed fairly well treating spiked real wastewater exhibited remarkable stability, only 3% decrease CBB efficiency after 10 continuous cycles 0.11% drop cathodic current per cycle. can be oxidative technology to tackle resource-constricted regions.
