| 摘 要： | 研究了乐果在颗粒物表面上吸附的动力学特征,观察了颗粒物的性质对吸附行为的影响.结果表明,乐果在3种颗粒物上的吸附过程均符合一级动力学规律,其相关系数在0.986 2～0.990 5,达到极显著水平.颗粒物的性质与吸附量相关分析发现,不同颗粒物对乐果的吸附程度是由颗粒物的有机质、粘粒、阳离子交换容量(CEC)和pH等理化特征综合作用的结果.pH对吸附行为影响的实验结果指出,随着体系的pH逐渐增大,颗粒物对乐果的吸附能力增强.

| Abstract: | Series of batch kinetic experiments were performed for aquesous phase adsorption of Rogor on three soil particle samples of Inner Mogolia. The first order reaction kinetics was adequate to represent all the rate study data; the correlation coefficient ranged between 0. 986 2-0. 990 5. The results were dependent on physical and chemical properties of the soil particles and that the amount adsorbed increased with pH, within the experimental range of pH 3-8. |
