Mechanism and Improvement of Electrocoagulation Technology for Removing Microplastics from Wastewater-Current Status and Future Directions
Electrocoagulation (EC) presents a highly efficient and sustainable solution for microplastic (MPs) removal from wastewater, offering advantages of operational simplicity, minimal sludge production, and reduced chemical usage compared to conventional methods. This review critically analyzes the current state and mechanisms of EC for MPs remediation, encompassing charge neutralization, sweep flocculation, electro-flotation, and oxidative degradation facilitated by electrochemically generated reactive species. The critical influence of operational parameters—electrode material (e.g., Al, Fe, composites), configuration, current density, pH, and inter-electrode spacing—on removal efficiency is evaluated. Crucially, the role of dissolved organic matter (DOM) in real matrices, impacting MPs removal via adsorption competition or synergistic co-removal, is addressed. Advancements in reactor design (e.g., turbulent/serpentine flow) and power supply (e.g., pulsed current mitigating passivation) are detailed. Hybrid EC systems (e.g., EC-electrooxidation, EC-membrane filtration) demonstrate superior MPs removal (> 95%). While highly effective (> 90% optimized), challenges regarding MPs properties (type, size, shape), DOM complexity, and scale-up requirements are identified. Future research priorities include optimizing configurations, elucidating degradation pathways, developing cost-effective electrodes, and pilot-scale validation for industrial implementation.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
