摘要：

将3-氨丙基三乙氧基硅烷(APTES)表面修饰的ZrO₂纳米颗粒添加到聚偏氟乙烯(PVDF)铸膜液中制备了PVDF/ZrO₂杂化膜, 应用SEM, TG-DTA和XRD对其结构进行了表征. 结果表明, ZrO₂纳米颗粒沉积在PVDF膜孔内和膜表面; ZrO₂的掺杂改变了PVDF膜孔径的大小, 杂化膜的孔径随着ZrO₂粒子负载量的增加而增大. 对牛血红蛋白(BHb)的吸附实验结果表明, PVDF/ZrO₂杂化膜对BHb的吸附量显著高于PVDF原膜, 当BHb初始浓度为150 μg/mL, pH=7, 吸附时间为45 min时, PVDF/ZrO₂杂化膜的平衡吸附量为0.181 mg/cm². 其吸附动力学符合一级动力学模型; 吸附等温线符合Langmuir等温方程式.

Abstract:

PVDF/ZrO₂ hybrid membranes was synthesized by blending the PVDF casting solution and ZrO₂ nanoparticles whose surface was modified by 3-aminopropyltriethoxysilane. Scanning electron microscopy(SEM), X-ray diffraction(XRD) and thermal analysis were used to character the membranes. The results showed that the functionalized ZrO₂ nanoparticles were deposited on the surface and entrapped into the inner pores of PVDF. The pore size of PVDF was affected by ZrO₂ additions, which were enlarged as the ZrO₂ loading amounts increased. The adsorption experiments of BHb showed that an enhanced adsorption capacity was observed for PVDF/ZrO₂ hybrid membranes. When the initial concentration of BHb was 150 μg/mL, the pH value was 7 and the contact time was 45 min, the maximum capacity of hybrid membrane was 0.181 mg/cm². Its adsorption kinetics was in accordance with the first order kinetics model, and the adsorption isothermal was fitted to the Langmuir equation.
