The major polluting aspects of our global fashion industries are the textile wastewater that turns black all our freshwater reservoirs. Nano-filtration through membrane technology is one of the biggest solutions of industrial wastewater treatment but the fouling of membrane is the major limitation of previous work. In this research, novel PVDF/MoS2-TNT (PMT) nanocomposite membranes were fabricated through a modified In-situ polymerisation phase inversion method. X-ray diffraction (XRD) analysis also confirmed the β-phase of PVDF within the developed PVDF/MoS2-TNT membrane. XPS analysis provides evidence about the presence of a specific chemical states of titanium nanotube and molybdenum disulphide which is involved in the photocatalytic degradation of pollutant molecules. Scanning electron microscope (SEM) shows that our membranes are porous in nature. PVDF/MoS2-TNT membranes exhibit excellent filtration efficiency (97%) for textile wastewater. The results and outcomes of the research demonstrate that PMT membranes have enormous potential in the commercial application of textile wastewater treatment.

用于光催化降解水中污染物的光响应单层MoS2纳米通道膜



全球时装业的主要污染源是纺织废水,它使我们所有的淡水水库变黑。膜纳滤技术是工业废水处理的最大解决方案之一,但膜的污染是以往工作的主要限制。在这项研究中,通过改进的原位聚合相转化方法制备了新型PVDF/MoS 2 -TNT (PMT) 纳米复合膜。 X射线衍射(XRD)分析还证实了所开发的PVDF/MoS 2 -TNT膜内PVDF的β相。 XPS 分析提供了有关钛纳米管和二硫化钼特定化学状态存在的证据,这些化学状态参与污染物分子的光催化降解。扫描电子显微镜 (SEM) 显示我们的膜本质上是多孔的。 PVDF/MoS 2 -TNT 膜对纺织废水表现出优异的过滤效率 ( 97%)。研究结果和成果表明,PMT膜在纺织废水处理的商业应用中具有巨大的潜力。
