Abstract
为探究不同生物炭对新烟碱类农药的吸附性能,寻求最佳的新烟碱类农药吸附材料,选取玉米芯、玉米秸秆、杨树枝、小麦秸秆、梧桐枝、花生壳6种生物质为原料,在300、500和700℃下制备得到18种生物炭.通过比较不同生物炭对吡虫啉、噻虫嗪、呋虫胺3种新烟碱类农药的吸附能力,筛选出了吸附效果较佳的生物炭,分别为700℃制备的玉米秸秆生物炭、小麦秸秆生物炭、杨树枝生物炭;吸附动力学和等温吸附研究表明,3种筛选生物炭对吡虫啉、噻虫嗪、呋虫胺的吸附过程符合准二级动力学模型、Langmuir模型和Freundlich模型.
In order to explore the adsorption properties of neonicotinoids by different biochars and identify the suitable materials to adsorb neonicotinoids,18 kinds of biochars derived from corn cob,corn straw,poplar branch,wheat straw,phoenix tree branch,and peanut shell were prepared at 300,500,and 700℃.By comparing the adsorption capacities of different biochars to imidacloprid,thiamethoxam,and dinotefuran,biochars with the better adsorption performance(corn straw biochar,wheat straw biochar,and poplar branch biochar prepared at 700℃)were screened out.Adsorption kinetic and isotherm studies showed that the adsorption of imidacloprid,thiamethoxam,and dinotefuran by three kinds of screened biochars were in accordance with the quasi-second-order kinetic,Langmuir,and Freundlich models.
