Abstract

Most parts of the earth are covered with water, but only 0.3% of it is available to living beings. Industrial growth, fast urbanization, and poor water management have badly affected the water quality. In recent years, a transition has been seen from the traditional (physical, chemical) wastewater treatment methods towards a greener, sustainable, and scalable membrane technology. Even though membrane technology offers a green pathway to address the wastewater treatment issue on a larger scale, the fabrication of polymeric membranes from toxic solvents is an obstacle in making it a fully green method. The concept of green chemistry has encouraged scientists to engage in research for new biodegradable and non-protic solvents to replace with already existing toxic ones. This review outlines the use of non-toxic solvents for the preparation of PVDF membranes and their application in membrane distillation and membrane crystallization.

膜蒸馏和膜结晶用PVDF膜制备的研究现状:面向无毒溶剂的使用。
地球的大部分地区都被水覆盖,但只有0.3%的水可供生物使用。工业发展、快速城市化和水资源管理不善严重影响了水质。近年来,从传统的(物理、化学)废水处理方法向更环保、可持续和可扩展的膜技术转变。尽管膜技术为大规模解决废水处理问题提供了一条绿色途径,但从有毒溶剂中制造聚合物膜是使其成为完全绿色方法的障碍。绿色化学的概念鼓励科学家从事新的可生物降解和非质子溶剂的研究,以取代现有的有毒溶剂。综述了无毒溶剂在PVDF膜制备中的应用及其在膜蒸馏和膜结晶中的应用。
