摘要
生物炭因其在碳封存和改良土壤方面的应用前景而受到广泛关注,全面了解其对农药吸附和环境行为的影响有利于发挥其在控制农药污染中的作用。利用"分配作用/表面吸附"相结合的机理探讨了生物炭对农药的吸附作用,以及生物炭特性、农药结构性质和土壤环境因素对吸附作用的影响,阐述了生物炭对调节农药在土壤中迁移、消解的研究进展。
Biochars have been paid much attention due to their application prospect in carbon sequestration and soil amend- ment. The comprehensive knowledge on their sorption to pesticides and influence on the environmental behaviors of pesticides is necessary for better utilization of biochars in controlling the pollution of pesticides. Using the combined ＂partition/adsorption＂ mechanism, we investigated the sorption of pesticides by biochars, and the influence of biochars＇ characteristics, pesticides＇ properties and soil environmental factors on the sorption of pesticides. The research advances of biochars on regulating the leaching and dissipation of pesticides in soils were introduced.
