| 摘 要： | 在实验室条件下,采用平衡振荡法在288 K2、98 K和308 K温度下对乙草胺在土壤中的吸附进行了研究。结果表明,乙草胺在土壤中的吸附符合Freundlich吸附等温线,吸附量随温度的增加而增加。通过对土壤吸附乙草胺的热力学特征进行研究发现,乙草胺在土壤中的吸附过程为自发的吸热反应。乙草胺在土壤吸附的推动力是配位基交换,属于化学吸附行为。

| Abstract: | The thermodynamic adsorption of soil to acetochlor was studied.The results showed that: the adsorption of acetochlor in soil fitted with Freundlich isotherm equation well,the adsorption capacity was increased with the increasing of temperature;the sorption process was spontaneous endothermic reaction and the force of concerted radical exchange was the driving force of sorption. |
