摘要:
应用Pickering HIPEs乳液聚合法,以CTs纳米粒子为乳液稳定粒子、OP-10为表面活性剂,制备了具有多孔结构的温敏阿莫西林(AMX)分子印迹吸附材料(PTMIPs)。运用多种方法对其理化性能进行了表征,结果表明材料具有稳定的多孔结构,平均孔径约为25 μm。吸附实验中PTMIPs对于AMX分子具有良好的选择吸附性能,pH为6.0时对AMX的吸附量达到最大值(16.27 μmol/g)。温敏性能实验结果表明PTMIPs的LCST约为32 ℃。PTMIPs吸附AMX的过程用Langmuir模型能更好地拟合实验数据(R2>0.96),表明以单分子层吸附为主。准二阶动力学模型对于PTMIPs的吸附过程有更高的拟合相关系数(R2>0.99)。5次吸附脱附后PTMIPs的吸附损失约为8.07%,有良好再生性能。
Abstract:
In this paper, CTs nanoparticles and surfactant OP-10 were applied to the preparation of porous temperature-sensitive Amoxicillin(AMX)imprinted adsorbents(PTMIPs)by Pickering HIPEs emulsion polymerization. Various methods were applied to characterize the physicochemical properties. The results indicated that PTMIPs possessed stable porous structure and the average pore size was about 25 μm. Adsorption experiments of PTMIPs also showed specific selection performance for AMX. At pH 6.0, AMX adsorption by PTMIPs reached a maximum value of 16.27 μmol/g. Temperature-sensitive experiment results indicated that the LCST of PTMIPs was about 32 ℃. The isotherm experimental data were better fitted by Langmuir model(R2>0.96), indicating the monolayer adsorption process. The adsorption kinetics was described better by the pseudo-second-order model(R2>0.99). After five adsorption-desorption recycle, the adsorption efficiency of PTMIPs was decreased about 8.07%, possessing a good regenerative performance.
