Generation, toxicity, and reduction of chlorinated byproducts: Overcome bottlenecks of electrochemical advanced oxidation technology to treat high chloride wastewater

Hualiang Feng et al.

Summary: In this study, the electrochemical advanced oxidation process (EAOP) was used to treat landfill leachate wastewater. The toxicities of the chlorinated byproducts generated during EAOP treatment were quantitatively assessed. The study found that active chlorine, chlorate, and perchlorate were the dominant chlorinated byproducts, with active chlorine being the most toxic. The settling process could spontaneously decompose the toxic active chlorine, and the use of a secondary bioreactor could reduce perchlorate and chlorate concentrations. It was also found that Pseudomonas and Thauera bacteria played key roles in the reduction of chlorate and perchlorate, respectively.

Production of Dichloroacetonitrile from Derivatives of Isoxaflutole Herbicide during Water Treatment

Jacqueline Rogers et al.

Summary: The herbicide isoxaflutole can directly contaminate drinking water and can also impact water quality by hydrolyzing to form the toxic disinfection byproduct dichloroacetonitrile (DCAN). In this study, we investigated the reaction of the active form diketonitrile with free chlorine and chloramine to form DCAN. Our findings suggest that increasing isoxaflutole use, especially with genetically modified isoxaflutole-tolerant crops, may lead to a higher concentration of the DCAN precursor during disinfection.

Electron cooling in graphene enhanced by plasmon-hydron resonance

Xiaoqing Yu et al.

Summary: Ultrafast spectroscopy experiments reveal that graphene electrons can transfer energy directly to liquid water without mediation from the crystal lattice. A quantum theory of solid-liquid heat transfer accounts for the water-specific cooling enhancement through a resonance between the graphene surface plasmon mode and water charge fluctuations. These findings provide direct experimental evidence of a solid-liquid interaction mediated by collective modes, supporting the theory of quantum friction and suggesting strategies for enhancing thermal conductivity in graphene-based nanostructures.

Formation of Targeted and Novel Disinfection Byproducts during Chlorine Photolysis in the Presence of Bromide

Devon Manley Bulman et al.

Summary: Bromide in water can lead to increased formation of disinfection byproducts during chlorine photolysis, which is an advanced oxidation process. The mechanisms and potential formation of disinfection byproducts (DBPs) under these conditions are not well understood. Our study investigated the generation of reactive oxidants and DBP formation during dark conditions, chlorine photolysis, and radical-quenched chlorine photolysis, with varying chlorine and bromide concentrations. We found that the formation of targeted and novel DBPs during chlorine photolysis may be limited in waters with elevated bromide.

Electro-Fenton and Induced Electro-Fenton as Versatile Wastewater Treatment Processes for Decontamination and Nutrient Removal without Byproduct Formation

Luz Estefanny Quispe Cardenas et al.

Summary: This study discovered the multifunctionality of electro-Fenton (EF) and induced EF (I-EF) processes in removing organics, pathogens, and phosphate without halogenated byproduct formation. The EF and I-EF processes used sacrificial anodes or induced electrodes to activate H2O2 produced from a gas diffusion cathode. Reactive chlorine species were eliminated by H2O2, preventing the formation of halogenated byproducts. The EF process showed high removal efficiencies for COD, carbamazepine, and phosphate, while also demonstrating broad-spectrum disinfection activities.

Impact of supporting electrolyte on electrochemical performance of borophene-functionalized graphene sponge anode and degradation of per-and polyfluoroalkyl substances (PFAS)

Nick Duinslaeger et al.

Summary: In this study, a graphene sponge anode functionalized with 2D boron (borophene) was used for electrochemical oxidation of C4-C8 per- and polyfluoroalkyl substances (PFASs). The borophene-doped graphene sponge anode showed higher removal efficiencies and electrochemical degradation of PFASs compared to the boron-doped graphene sponge anode. This research demonstrates the possibility of achieving efficient degradation of PFASs in complex and brackish streams using a low-cost graphene sponge anode.

Minimizing toxic chlorinated byproducts during electrochemical oxidation of Ni-EDTA: Importance of active chlorine-triggered Fe(II) transition to Fe (IV)

Haolin Xu et al.

Summary: This study presents a new strategy to minimize the release of chlorinated byproducts during electrochemical oxidation. By establishing a dual mixed metal oxide/iron anode system, it achieved higher destruction rate and more pronounced removal of Ni-EDTA. Fe(IV) generated from this system was responsible for reducing chlorinated byproducts and decreasing the acute toxicity of the treated solution. The Fe(IV)-dominated dual-anode system also showed superior performance in removing multiple pollutants in real electroless plating effluent.

Graphene-based sponges for electrochemical degradation of persistent organic contaminants

Luis Baptista-Pires et al.

Summary: Graphene-based sponges doped with atomic nitrogen and boron were effective in the electrochemical degradation of organic contaminants in low-conductivity electrolytes, achieving >90% contaminant removal. The anodic and cathodic reactions involved direct electron transfer, formation of O-3, and OH radicals generated by H2O2 decomposition. The sponge also showed low electrocatalytic activity towards chloride, with no chlorate and perchlorate formation in the presence of NaCl.
