| 摘 要： | 研究了双酚A在土壤表面的吸附行为,探讨pH值、土壤用量、双酚A的起始浓度、腐殖酸、温度对吸附作用的影响.实验结果表明:双酚A在土壤表面的吸附平衡时间约需2h,双酚A在土壤表面的吸附行为可以较好地用Langmuir型吸附等温式来描述,吸附量随着pH值的增加而减小,随着土壤量的增加而增加.热力学计算表明升高温度不利于吸附.

| Abstract: | The adsorption properties of bisphenol A(BPA) in soil were studied.Effects of some factors,such as pH values and dosages of soil,initial concentration of the BPA,absorbing time,temperature,on the removing of BPA from water solution were investigated.The results show that the time of BPA adsorption equilibrium was reached within 2 hours.The adsorption of BPA on soil can be described by the Langmuir isotherms.The adsorption amount of BPA decreases with in-creasing pH values and increases with increasing dosage of soil.The increased temperature doesn't benefit the adsorption of BPA on soil. |
