| 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. |
