Special Issue Information

Dear Colleagues,

The special issue of Water aims to publish research involved electro-assisted technologies employed to purify drining water. The subjects are listed in the followings and not limited.

Drinking water is one of the most significant resources for our human beings to survive, manufact and develop. Beside the conventional processes are emplyed to clarify source water, various advaced technologies are adopted to remove persistent organic or inorganic chemicals that can pass through coagulation, sedmentaion, filtration and disinfection. Electro-assisted water treatment technologies attracted more and more attention including electro-coagulation, electro-filtration, electro-oxidation and other combined processes. Among those above process, electro-Fenton/utra-violet and other advanced oxidation process have outstanding perfomance in degradation of micro- persistant contaminants. Usually, the persitent contaminants include pesticide, food additives, pharmaceuticals and personal care products, and others which ocurred in the water enviroment ubiquitously. Elctro-coagulation has advantages in treating source water with lower turbidity and temperature that chemical coagulation, and is employed to impove membrane performance. Electro-assisted dehalogenation occurred on cathode, which can remove chlorinated/brominated organic compounds  through reduction. Dehalogenation favors the disinfection by-products abatement which formed in the disinfection process by using chlorine and pose hazard potential to human health.

To help the researchers get more knowledge on drinking water treatment by electro-assited technologies, and to promote academic exchange, please submit your recent research result.

Electrochemical reduction is a promising strategy for the dechlorination of halogenated organic compounds, offering advantages such as enhanced electron transfer efficiency and increased hydrogen atom concentration. It has garnered significant attention for application in mitigating halogenated disinfection by-products (DBPs) in drinking water, owing to its high efficiency and simple operation. In this study, trichloroacetic acid (TCAA), a representative DBP, was selected as the target contaminant. A novel composite cathode comprising a metal–organic framework MIL-53(Fe)@C supported on an Nd magnet (MIL-53(Fe)@C-MAG) and its dechlorination performance for TCAA were systematically investigated. The innovative aspect of this study is the magnetic attachment of the MOF catalyst to the carbonized cathode surface treated through carbonization, which fundamentally differs from conventional solvent-based adhesion methods. Compared to the bare electrode, the MIL-53(Fe)@C-MAG achieved a TCAA removal efficiency exceeding 96.03% within 8 h of contact time. The structural characterization revealed that the α-Fe0 crystalline phase serves as the primary active center within the MIL-53(Fe)@C catalyst, facilitating efficient electron transfer and TCAA degradation. The scavenger experiments revealed that TCAA reduction involves a dual pathway: direct electron transfer and atomic hydrogen generation. The modified MIL-53(Fe)@C-MAG electrode exhibited robust electrolytic performance over a broad pH range of 3–7, with TCAA removal efficiency showing a positive correlation with current density within the range of 10–50 mA/cm2. Furthermore, the electrode maintained exceptional stability, retaining more than 90% removal efficiency after five consecutive operational cycles. The versatility of the system was further validated by the rapid and efficient dechlorination of various chlorinated DBPs, demonstrating the broad applicability of the electrode. The innovative magnetic composite electrode demonstrates a significant advancement in electrochemical dechlorination technology, offering a reliable and efficient solution for the purification of drinking water contaminated with diverse halogenated DBPs. These results provide valuable insights into the development of electrolysis for dechlorination in water treatment applications. Full article
