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。
The themodynamic adsorption of soil to acetocldor 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 endothennic reaction and the force of concerted radical exchange was the driving force of sorption.
