农田土壤中全氟化合物的迁移转化与污染控制技术研究进展
Advances in migration,transformation,and pollution control technologies of perfluoroalkyl substances in farmland soils:a review
摘要
Abstract
This article provides an overview of the migration and transformation of per-and polyfluoroalkyl substances in farmland soils,as well as control technologies such as immobilization/stabilization,electrochemical oxidation,plant/microbial restoration,and soil leaching.The key influencing factors,advantages and disadvantages,and future development directions of these methods are also discussed and summarized.However,the complexity of PFAS,their chemical and thermal stability,and the impact of various technologies on soil structure,fertility,crop growth,and toxicity make the remediation of PFAS in farmland soils challenging.This article also points out the limitations of various remediation techniques in degrading perfluorinated compounds.The immobilization/stabilization technology can fix PFAS through adsorbents and reduce its mobility,but the immobilization material has a limited lifespan and long-term stability still needs further research.Although plant/microbial remediation technology is environmentally friendly,its response cycle is relatively slow,and more research is needed to explore its potential in long-term remediation.Electrocatalytic oxidation technology exhibits high efficiency in treating PFAS,but faces high costs and energy consumption issues,especially in large-scale applications where electricity consumption and operating costs may become limiting factors.Although soil leaching can effectively remove PFAS,the organic solvents used may remain in the soil,potentially affecting soil fertility and ecological environment.Therefore,the ecological toxicity of the solvents must be evaluated before application.As the development of new PFAS remediation technologies is crucial for addressing environmental pollution,enhancing material performance,promoting sustainable development,and advancing environmental protection technologies,the article suggests focusing on the research of innovative remediation technologies,such as mechanical destruction and electron beam techniques.关键词
