Enhanced and irreversible sorption of pesticide pyrimethanil by soil amended with biochars
Biochar derived from partial combustion of vegetation is ubiquitous and potentially eective in sequestration of environmental contaminants.Biochars were prepared by burning of red gum (Eucalyptus spp.) woodchips at 450 and 850°C (labeled as BC450 and BC850).These two biochars were found to possess markedly dierent properties in terms of surface area and porosity.Short-term equilibration tests (24 hr) were conducted to assess the sorption-desorption behavior of pyrimethanil in the soil amended with various amounts of biochar of each type,with a special focus on the desorption behavior of the sorbed pesticide through four times successive desorption by dilution.Sorption coecient and isotherm nonlinearity of the amended soils progressively increased with the content of biochar in the soil.Biochar BC850 with higher surface area and microporosity showed a stronger eect on the reversibility of sorption pesticide.The soils amended with 5% BC450 and 1% BC850 had nearly the same sorption capacity for pyrimethanil; however,their desorption processes were very dierent with 13.65% and 1.49% of the sorbed pesticide being released,respectively.This study suggested that biochar in soil could be an important factor for immobilization of a pesticide and thus a ecting its environment fate in soil.

强的、不可逆的农药吸附pyrimethanil土biochars修改
Biochar源自部分燃烧的植被是普遍存在的和潜在的eective游离于环境污染.Biochars由燃烧的红色胶(桉树木片.)在450和850摄氏度(贴上BC450和BC850).这两个biochars发现具有明显的dierent性质的表面积和孔隙率.短期求测试(24小时)进行了评估sorption-desorption pyrimethanil行为在土壤中的不同数量的biochar修改的各类型,并特别着重于解吸行为的sorbed农药通过四次被稀释连续解析.coecient吸附等温非线性修正,逐步提高土壤的内容biochar在土壤里.Biochar BC850具有更高的表面积和microporosity表现较强的除相反的吸附农药.BC450土壤修改了5%,1%的BC850几乎相同的吸附能力;然而,他们pyrimethanil解吸工艺是非常dierent 1.49%与13.65%的sorbed农药,被释放.该研究表明,biochar可以在土壤的重要因素,因此固定了一个农药在土壤环境的命运如何.
