摘要
用间歇法研究了红壤和人工合成的铝氧化物吸附除草剂(氯磺隆、苄嘧磺隆)的动力学特性。结果表明:土壤和氧化物对除草剂的吸附均在较短的时间内达到平衡。用五种模型对土壤和氧化物的吸附动力学过程进行了描述,其中最优模型是一级动力学方程。两种除草剂在两种供试样品中的吸附量均有差别。
Kinetics of sulfonylurea herbicides including chlorsulfuron and bensulfuron-methyl adsorption were investigated on soil and Al oxide using batch techniques.Results indicated that the equilibrium was reached in early stage of contact between oil oxide and herbicides.Among five models that describe adsorption kinetics of herbicides,the first order dynamic equation was the optimal.The amount of BSM adsorption on the tested samples was different.
