摘要
在实验室条件下,采用平衡振荡法在2882、98和308 K温度下对克百威在土壤中的吸附进行了研究。结果表明,克百威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减少;土壤吸附克百威的热力学特征研究发现,克百威在土壤中的吸附过程为自发的放热反应;克百威在土壤吸附的推动力是氢键力,无配位基交换、化学键等强的作用力。
A study was carried out to investigate the thermodynamic adsorption of carbofuran in soil under 288,298 and 308 K. The results showed that the adsorption of carbofuran in soil was fitted with Freundlich isotherm equation well and the adsorption capacities were decreased with the increment of temperature.The process was spontaneous exothermic reactiun, without strong action force of concerted radical exchange and chemical bond, and the force of hydrogen bond was the driving force of sorption.
