摘　　要：农药的广泛高剂量使用对生物产生严重的毒性作用,造成严重的土壤污染和水污染。农药污染问题日益突出,迫切需要经济、有效的农药污染土壤修复处理技术加以解决。生物炭具有比表面积大、孔隙度高、吸附能力强等特点,可以吸附污染土壤中的农药,改善土壤状况,是一种具有广阔应用前景的生物材料。近年来,人们通过制备改性生物炭来提高生物炭的理化性能和吸附性能,为生物炭的应用开辟了新道路。详细阐述了生物炭的特性、新烟碱类农药的危害、生物炭对新烟碱类农药的吸附以及生物炭再生方法,以期为修复新烟碱类农药污染提供一定的参考和指导。此外,通过比较生物炭再生方法,为今后选择经济、有效、简便的生物炭再生应用提供参考。With the development of agricultural modernization,many pesticides have been applied to fields.The extensive and high-dose use of pesticides has produced serious toxic effects on organisms,resulting in serious soil and water pollution.The problem of pesticide pollution is becoming more and more serious.Therefore,economic and effective remediation technology of pesticide-contaminated soil is urgently needed.Biochar has the characteristics of large specific surface area,high porosity and strong adsorption capacity,which can adsorb pesticides in polluted soil and improve soil conditions.It is a kind of biomaterial with broad development prospects.In recent years,people have improved the physical and chemical properties and adsorption properties of biochar by preparing modified biochar,which has opened up a new way for the application of biochar.In this paper,the characteristics of biochar,the harm of neonicotinoid pesticides and the adsorption of neonicotinoid pesticides by biocharare reviewed.At the same time,the reproduction methods of biocharare summarized.The summary can provide some reference and guidance for repairing the pollution of neonicotinoid pesticides,hoping to reduce the pollution of neonicotinoid pesticides in soil environment.In addition,by comparing the methods of biochar regeneration,it provides a reference for choosing an economical,effective and simple application of biochar regeneration in the future.
