초록

Innovations for separation via membranes are extremely energy-efficient, and through the previous decade, attention to this technology has spiked tremendously. Biopolymers are becoming widely recognized as membrane materials since they are sustainable. Furthermore, the second most common biopolymer, chitin, is the source of chitosan, which has several benefits that make it ideal for the construction of membranes. This review article presents an evaluation of current developments in the utilization of chitosan membranes. The applications of interest in this review are nanofiltration, pervaporation and ion exchange. The chitosan based nanofiltration membranes are comprehensively reviewed with respect to various factors (e.g., solvent, pH resistant, etc.). The development of water permselective, organic permselective, and organic-organic separation films, as well as its permeability and segregation properties, are addressed in pervaporation (PV) section.
