ABSTRACT
Micro/nano plastics ï¼M/NPsï¼ are widely dispersed in the soilï¼ atmosphereï¼ and water environment due to their small particle sizeï¼ easy adsorptionï¼ and strong migrationï¼ and have been detected in all major water bodies in recent years. As a type of emerging pollutantï¼ the physiological toxicity of M/NPs has a great impact on human health. The current bottleneck in this research field lies in the precise detection and efficient removal of M/NPs. Electrochemical technologyï¼ owing to its advantages of simple portabilityï¼ sensitivityï¼ and low cost in the detection of M/NPsï¼ has the advantages of environmental friendlinessï¼ controllable reactionï¼ and high efficiency in the removal of M/NPsï¼ demonstrating enormous application potential. Based on the pollution status of M/NPsï¼ the application of electrochemical technology to the detection and removal of M/NPs in the water environment was elaborated and summarized. The electrochemical sensing methods of M/NPs and the principles and characteristics of sensor recognition of M/NPs were analyzed. The removal efficiency and influencing factors of M/NPs in water by electro-flocculationï¼ electro-adsorptionï¼ electro-oxidationï¼ and electro-reduction technologies were also discussed. The results indicated that the detection of M/NPs particles using electrochemical sensing methods exhibited good characterization performanceï¼ and M/NPs could be efficiently removed through electrochemical techniques such as electrocoagulationï¼ electro-adsorptionï¼ electro-oxidationï¼ and electro-reduction. The influencing factors of electrochemical technology on the detection and removal of M/NPs were mainly related to sensor devicesï¼ electrode materialsï¼ material interface regulationï¼ parameter conditionsï¼ and reactor systems. In the futureï¼ researchers should focus on the design of sensorsï¼ the development of electrode materialsï¼ and the optimization of reaction processesï¼ which are expected to realize the application of M/NPs from laboratory detection and removal to actual water bodies.
