This research used the phase inversion approach to construct polyvinyl chloride nanocellulose@titanium aluminate nanocomposite membranes (PVC/NC@TALCM) to adsorb and filter dye from wastewater. FTIR, XRD, and SEM were used to determine the adsorptive nanocomposite membrane that had been synthesized. The thermal and electrical properties measurements were carried out using a static system. The influence of several adsorbent dosages, pH, and dye concentrations on the nanocomposite membrane's adsorption ability was investigated. Using a dead-end filtration system, the PVC-NC@TALCM was evaluated as a pressure filtration membrane system. It was found that 98.6% of MB dye was removed by PVC-NC@TALCM membrane, which was loaded with 5% titanium aluminate at pH 10. The kinetic adsorption studies indicated that the adsorption of MB onto the PVC-NC@TALCM nanocomposite membrane obeys pseudo-second-order that indicates the chemosorption process. The isotherm data were described using Freundlich and Langmuir models, and the Freundlich isotherms were shown to be more closely match the experimental data than the Langmuir model. Finally, the PVC-NC@TALCM nanocomposite membrane was economical, environmentally friendly, and self-cleaning.
这项研究采用相反转方法构建聚氯乙烯纳米纤维素@钛酸铝纳米复合材料膜（PVC/NC@TALCM），以吸附和过滤废水中的染料。采用傅里叶变换红外光谱（FTIR）、X 射线衍射（XRD）和扫描电子显微镜（SEM）对合成的吸附性纳米复合膜进行了表征。采用静态系统对其热性能和电性能进行了测量。考察了不同吸附剂用量、pH 值和染料浓度对纳米复合膜吸附能力的影响。采用死端过滤系统对 PVC-NC@TALCM 进行了评价，作为压力过滤膜系统。结果表明，在 pH 值为 10 时，负载 5%钛酸铝的 PVC-NC@TALCM 膜对 MB 染料的去除率达到 98.6%。吸附动力学研究表明，MB 在 PVC-NC@TALCM 纳米复合膜上的吸附符合准二级动力学模型，表明该吸附过程为化学吸附。等温线数据用 Freundlich 和 Langmuir 模型进行了描述，结果表明 Freundlich 等温线更符合实验数据，而 Langmuir 模型则不然。最后，研究表明 PVC-NC@TALCM 纳米复合膜具有经济性、环境友好性和自清洁性。
