| 摘 要： | 在实验室条件下,采用平衡振荡法研究288、298和308K温度下五氯酚钠在土壤中的吸附热力学特征。结果表明,五氯酚钠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;五氯酚钠在土壤中的吸附过程为自发的放热反应;五氯酚钠在土壤中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。

| Abstract: | A study on the thermodynamic adsorption of sodium pentachlorophenol (PCP-Na) in soil was carried out under the condition of temperature(288 K,298 K and 308 K). The results showed that the adsorption of PCP-Na in soil fitted with Freundlich isotherm equation well; the adsorption capacity was decreased with increasing temperature; the sorption process was spontaneous exothermic reaction; there was not strong action force of concerted radical exchange and chemical bond and the force of hydrogen bond was the driving force of sorption. |
