| 摘 要： | 通过改良Hummer方法制备了氧化石墨烯(GO),通过批量平衡试验考察了其对泰乐菌素的吸附特性和机制。研究结果表明:GO对泰乐菌素的吸附在24 h可达到动态吸附平衡,吸附动力学可用拉格朗日二级动力学模型较好地拟合;吸附等温线用线性吸附模型可以较好地拟合;吸附随着p H值的升高而降低,随着离子强度的增大而减弱。

| Abstract: | In this study, graphene oxide(GO) was prepared by the modified Hummer approach. The adsorption characteristics and mechanisms of GO to tylosin were investigated via a series of batch equilibrium experiments. The results indicated that the dynamic adsorption of tylosin on GO reached equilibrium at 24 h. The kinetics of adsorption was described well by the pseudo-second-order model, and Henry models were more suitable for the sorption isotherm. Besides, the adsorption capacity increased as the decreasing pH whereas it decreased with the increase of ionic strength. |
