Abstract

In this study, amino functionalized cellulose nanocrystals–polyethersulfone nanocomposite membrane (A-CNC/PES) based on agricultural waste was used for the removal of diazinon (DZ) from aqueous solution. The fabricated membrane has been characterized via attenuated total reflectance-Fourier transform infrared (ATR-FTIR), scanning electron microscopy (SEM), dispersive X-ray spectrometer (EDX), X-ray diffractometer (XRD), thermal gravimetric analysis (TGA), water contact angel (WCA), porosity, and mean pore radius. The effect of variables, such as initial DZ concentration, pH, and A-CNC content, on the membrane performance was optimized using response surface methodology (RSM) through central composite design (CCD). The results indicated that the additive had the most significant effect on the hydrophilicity improvement, reducing surface roughness, and reducing fouling. The highest removal efficiency of A-CNC/PES membrane for DZ was about 99.3% (at A-CNC: 0.2 wt%), and more than three-fold water flux improvement (27.3 versus 8.3 kg/m².h for unmodified membrane) was attained. The results of antifouling test confirmed that the A-CNC/PES membranes had a high-flux recovery (FRR: 90.05%). This study may provide promising insights for the development of next generation of agricultural waste-based nanocomposite membrane in the water and wastewater treatment.

通过葡萄枝衍生纤维素纳米晶体/聚醚砜纳米复合膜去除水溶液中的二嗪农：性能、表征和建模

本研究利用基于农业废弃物的氨基功能化纤维素纳米晶-聚醚砜纳米复合膜（A-CNC/PES）去除水溶液中的二嗪农（DZ）。通过衰减全反射-傅立叶变换红外光谱（ATR-FTIR）、扫描电子显微镜（SEM）、色散 X 射线光谱仪（EDX）、X 射线衍射仪（XRD）、热重分析（TGA）、水接触天使（WCA）、孔隙率和平均孔半径对制成的膜进行了表征。通过中心复合设计（CCD），使用响应面方法（RSM）优化了初始 DZ 浓度、pH 值和 A-CNC 含量等变量对膜性能的影响。结果表明，添加剂对改善亲水性、降低表面粗糙度和减少污垢的影响最为显著。A-CNC/PES 膜对 DZ 的最高去除率约为 99.3%（A-CNC：0.2 wt%），水通量提高了三倍多（27.3 而未改性膜为 8.3 kg/m2.h）。防污测试结果证实，A-CNC/PES 膜具有高通量恢复能力（FRR：90.05%）。该研究为开发下一代基于农业废弃物的纳米复合膜在水和废水处理中的应用提供了很好的启示。图文并茂的摘要利用葡萄枝衍生的 CNCs-PES 纳米复合膜高效去除水溶液中的二嗪农农药。
