Abstract

Polymeric membranes have garnered remarkable attention, attributed to the significant breakthrough in the filtration of oily wastewater. However, the major setbacks of pristine polymeric membranes include susceptibility to fouling and chemical instability. Addressing such issues, this work focusses in the modification of polymer membranes using a metal oxyhalide, such as Bismuth oxychloride (BiOCl). This modification not only enhances water purification capabilities but also strengthens the membrane, protecting it from environmental deterioration and extending its lifespan. BiOCl was integrated into an electrospun pristine nanofibrous polymeric membrane using hydrothermal technique. The synthesized membrane matrix displayed superhydrophilicity and underwater superoleophobicity, effectively separating oil-in-water mixtures and emulsions. Moreover, BiOCl was effectively utilized to assess organic pollutant adsorption and degradation through photocatalysis. In addition, the membrane exhibited exceptional recyclability and withstood harsh conditions, contributing to its mechanical stability. The numerous advantages, enhance the effectiveness of BiOCl modified membrane in water pollution remediation.

用于协同油水分离和降解染料的 BiOCl-PVDF 纳米纤维膜

聚合膜在过滤含油废水方面取得了重大突破，因而备受关注。然而，原始聚合物膜的主要缺点包括易结垢和化学性质不稳定。为解决这些问题，本研究重点使用金属氧卤化物（如氧氯化铋（BiOCl））对聚合物膜进行改性。这种改性不仅能提高水净化能力，还能增强膜的强度，使其免受环境恶化的影响，并延长其使用寿命。利用水热技术将 BiOCl 集成到电纺原始纳米纤维聚合物膜中。合成的膜基质具有超亲水性和水下超疏水性，能有效分离水包油混合物和乳液。此外，BiOCl 通过光催化被有效地用于评估有机污染物的吸附和降解。此外，该膜还表现出卓越的可回收性，并能经受苛刻条件的考验，因而具有机械稳定性。这些优点提高了 BiOCl 改性膜在水污染修复中的有效性。
