| 摘 要： | 在微波无极灯下将烯氧基瓜环固载到巯基硅胶(MSG)上,制得固载化瓜环(ACB6]-SG).通过红外光谱表征固载产物,并研究固载化瓜环对磺胺间甲氧嘧啶(SMM)的吸附性能.结果表明,SMM在固载化瓜环上的吸附基本在2 min内即可达到平衡；Henry方程和Freundlich方程均能较好地拟合SMM在固载化瓜环和巯基硅胶上的等温吸附曲线,但是SMM在固载化瓜环上的吸附主要是在瓜环中的分配,而SMM在巯基硅胶上的吸附则主要是多分子层的表面吸附作用；SMM在固载化瓜环上的平衡吸附量远大于在巯基硅胶上的平衡吸附量；SMM在两者上的吸附过程是一个放热过程,温度越低吸附效果越好. |

| Abstract: | 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. |
