%X Cucurbit6]uril anchored silica gel (ACB6]-SG) was produced by anchoring perallyloxy-cucurbit6]uril onto 3-mercaptopropyl-functionalized silica gel (MSG) under a microwave electrodeless lamp and was characterized by infrared spectrum analysis. The adsorption behaviors of sulfamonomethoxine (SMM) on ACB6]-SG and MSG were studied. The results showed that the adsorption of SMM on ACB6]-SG reached equilibrium in 2 min. The adsorption of SMM on ACB6]-SG and MSG could be well described by both the Henry model and the Freundlich model. However, the adsorption of SMM on ACB6]-SG was mainly partition processes of SMM in the cucurbit6]uril, whereas the adsorption of SMM on MSG occurred mainly on the multilayer molecular surface of ACB6]-SG. Furthermore, the adsorption amount of SMM on ACB6]-SG at equilibrium was much higher than that on MSG. The adsorption of SMM on both ACB6]-SG and MSG was an exothermic process, in which the lower the temperature was, the higher the adsorption efficiency.
