摘要

本研究旨在利用电容去离子技术研究岩石天然金属氧化物(MO)包埋活性炭(AC)电极对革兰氏阴性(大肠杆菌)和革兰氏阳性(金黄色沙门氏菌)细菌的抑菌活性。通过在1.2 V电势差下进行240 min (4 h)的间歇模式实验,对制备的AC/MO电极的脱盐和消毒性能进行了评价。结果表明,AC/MO电极对Nduruma溪流(天然水)现场水的大肠杆菌和金黄色葡萄球菌的去除率分别达到100%和60%。细菌的去除机制归因于电容脱离子(CDI)过程和物理吸附。该研究突出了AC/MO电极材料作为CDI工艺有效抗菌剂的潜力,这可能对水净化和消毒新技术的开发具有重要意义。

Naturally occurring metal oxides from rocks as capacitive deionization electrode material for antibacterial activities
The present study aimed to investigate the efficacy of activated carbon (AC) electrode embedded with naturally occurring metal oxides (MO) from rocks for antibacterial activities against both gram-negative ( Escherichia coli ) and gram-positive ( Salmonella aureus ) bacteria using capacitive deioniza-tion technique. The desalination and disinfection performance of the fabricated AC/MO electrode was evaluated through the batch mode experiments conducted at a potential difference of 1.2 V for 240 min (4 h). The results revealed that the AC/MO electrode achieved a complete removal efficiency of 100% for E. coli and 60% for S. aureus in the field water collected from Nduruma stream (natural water). The bacterial removal mechanism was attributed to the capacitive deion-ization (CDI) process and physical adsorption. The study highlights the potential of AC/MO electrode material as an effective antibacterial agent for the CDI process, which may have significant implications for the development of new technologies for water purification and disinfection.
