摘要
利用平衡吸附法研究了苄嘧磺隆在高岭土、针铁矿、水铁矿、非晶型氢氧化铝及水钠锰矿表面的吸附以及氯离子对吸附的影响。结果表明 ,供试粘土矿物及氧化物对苄嘧磺隆的吸附均符合Langmuir方程 ,最大吸附量大小顺序为 :非晶型氢氧化铝 >针铁矿 >水铁矿 >水钠锰矿 >高岭石 ,且吸附量随氯离子浓度的增加而降低。
The adsorption of sulfonylurea herbicide bensulfuron -m ethyl by kaolinite, goethite, ferrihydrite, amorphous alumina ,birnessite and t he effects of Cl - on the adsorption were examined. The results indicated that the adsorption was according to the Langmuir equation, the maximum absorbing cap acities were that amorphous alumina > goethite > ferrihydrite > birnessite > kao linite. The absorbing capacities decreased by increase of the concentrations of Cl -.
