This work introduces a novel synergistic approach for enhanced scale formation inhibition in desalination processes by employing a PVC-PVA@Chitosan Quantum Dot (PVA-PVC@CS QD) membrane, advancing sustainable water purification technologies further. The membrane's unique composition surpasses conventional membranes by fusing the exceptional properties of chitosan quantum dots with the robustness of polyvinyl alcohol (PVA) and polyvinyl chloride (PVC). The study investigates the mechanical, thermal, and electrical properties of the membrane in order to completely understand its behavior in desalination applications, as well as how well it inhibits the formation of scale, particularly calcite scale. In water purification systems, the membrane's durability and fouling resistance, which are assessed mechanically, are critical to long-term performance. Ion transport is facilitated by the membrane's capacity to maintain selectivity and its ability to support efficient desalination processes is assessed by examining its electrical properties. Experimental results demonstrate that the PVA-PVC@CS QD membrane outperforms conventional membranes in terms of scale inhibition due to the synergistic interactions among its constituents.
这项工作介绍了一种新颖的协同方法,通过使用聚氯乙烯-聚乙烯醇@壳聚糖量子点(PVA-PVC@CS QD)膜来增强海水淡化过程中的结垢抑制,进一步推动可持续水净化技术的发展。该膜独特的组成通过将壳聚糖量子点的优异性能与聚乙烯醇(PVA)和聚氯乙烯(PVC)的坚固性相融合,超越了传统膜。该研究调查了该膜的机械、热和电性能,以便全面了解其在海水淡化应用中的行为,以及它抑制结垢(特别是方解石垢)的效果。在水净化系统中,通过机械评估的膜的耐久性和抗污染性对于长期性能至关重要。膜保持选择性的能力促进了离子传输,通过检查其电性能来评估其支持高效海水淡化过程的能力。实验结果表明,由于其成分之间的协同相互作用,PVA-PVC@CS QD膜在结垢抑制方面优于传统膜。
