摘要
该研究调查了用 1.0 wt.% 氧化石墨烯(GO)改性的聚砜(PSF)中空纤维(HF)混合基质膜的污垢倾向。通过扫描电子显微镜(SEM)、原子力显微镜(AFM)、水接触角(WCA)和机械评估,研究了未经处理和经 GO 改性的 PSF 高频膜的结构特性。过滤实验包括纯水和模型污染物,如牛血清白蛋白(BSA)、腐植酸(HA)、大肠杆菌和水包油乳液。GO 改性膜的防污性能显著提高,在含有 HA 和油的情况下,其初始纯水通量恢复了 90% 以上,表明其具有很强的抗不可逆污垢能力。此外,GO 改性膜还显示出卓越的油分离效率。然而,两种类型的膜对 BSA 的污垢参数相似,这表明 GO 不会显著影响膜与 BSA 的相互作用。两种类型的膜对大肠杆菌都有很高的截留能力,GO 的添加并没有带来明显的改善。这项研究强调了 GO 改性 PSF 高频膜在提高防污性能和油分离效率方面的潜力。
Membranes fouling propensity of PSF/GO hollow fiber mixed matrix membranes for water treatment ultrafiltration application.
The study investigated the fouling propensity of polysulfone (PSF) hollow fiber (HF) mixed matrix membranes modified with 1.0 wt.% graphene oxide (GO). Using scanning electron microscopy (SEM), atomic force microscopy (AFM), water contact angle (WCA), and mechanical assessments, the structural characteristics of both untreated and GO-modified PSF HF membranes were examined. Filtration experiments included pure water and model contaminants such as bovine serum albumin (BSA), humic acid (HA), E. coli, and oil-in-water emulsion. The GO-modified membranes demonstrated a significant enhancement in antifouling performance, recovering over 90% of their initial pure water flux with HA and oil, indicating high resistance to irreversible fouling. Additionally, the GO-modified membranes showed superior oil separation efficiency. However, fouling parameters for BSA were similar for both membrane types, suggesting that GO does not significantly affect membrane-BSA interactions. Both types of membranes displayed high retention capabilities for E. coli, with no noticeable improvement due to GO addition. This study highlights the potential of GO-modified PSF HF membranes in enhancing antifouling performance and oil separation efficiency.
