In this study, polymer membrane(s) impregnated with carbon nanotubes (CNTs) were developed, characterized and evaluated for removing phenolic compounds from olive mill wastewater; thus, protecting the environment and public health. Polyethersulfone/functionalized, multi-walled carbon nanotube (PES/fCNTs) membranes were synthesized via the phase inversion method using PES and acid-treated CNTs. The prepared membranes were then characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR) and contact angle. Results obtained from this study indicate a more hydrophilic surface for the prepared PES/fCNTs membranes, with a higher pure water flux compared to the polyethersulfone (PES) membranes. In addition, the amount of fCNTs in the membranes was found to be the most significant factor affecting the morphology and water flux of the membranes. The PES/fCNTs membranes at 1 bar with 0 wt.% and 1 wt.% of CNTs showed water flux of 37.8 and 69.71 kg/h.m, respectively. In addition, PES/fCNTs membranes with 0.5 wt.% fCNTs showed the highest total phenol content removal of 74%.

在本研究中，开发了浸渍有碳纳米管（CNT）的聚合物膜，对其进行了表征和评估，以去除橄榄油厂废水中的酚类化合物，从而保护环境和公众健康。通过相转化法，使用聚醚砜（PES）和酸处理的碳纳米管合成了聚醚砜/功能化多壁碳纳米管（PES/fCNTs）膜。然后通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和接触角对制备的膜进行表征。本研究获得的结果表明，制备的PES/fCNTs膜具有更亲水性的表面，与聚醚砜（PES）膜相比，纯水通量更高。此外，发现膜中fCNTs的含量是影响膜形态和水通量的最主要因素。在1巴压力下，含0 wt.%和1 wt.% CNTs的PES/fCNTs膜的水通量分别为37.8和69.71 kg/h·m²。此外，含0.5 wt.% fCNTs的PES/fCNTs膜对总酚含量的去除率最高，为74%。
