“…The adsorption capacity of the chitosan membranes depends on the binding ability of metal ions with the amino groups of the chitosan, degree of deacetylation, and also density of amino groups on the surface [ 13 ]. Another important factor for the adsorption capacity of chitosan membranes are its physical properties such as surface area, volume of the pore, density, and elemental composition [ 274 ]. It proves, also, that process factors such as temperature, pH, presence of anion or cation, and degree of combination are very important in the chitosan processing.…”

During the past few years, researchers have focused their attention on developing innovative nanocomposite polymeric membranes with applications in water purification. Natural and synthetic polymers were considered, and it was proven that chitosan-based materials presented important features. This review presents an overview regarding diverse materials used in developing innovative chitosan-based nanocomposite polymeric membranes for water purification. The first part of the review presents a detailed introduction about chitosan, highlighting the fact that is a biocompatible, biodegradable, low-cost, nontoxic biopolymer, having unique structure and interesting properties, and also antibacterial and antioxidant activities, reasons for using it in water treatment applications. To use chitosan-based materials for developing nanocomposite polymeric membranes for wastewater purification applications must enhance their performance by using different materials. In the second part of the review, the performance’s features will be presented as a consequence of adding different nanoparticles, also showing the effect that those nanoparticles could bring on other polymeric membranes. Among these features, pollutant’s retention and enhancing thermo-mechanical properties will be mentioned. The focus of the third section of the review will illustrate chitosan-based nanocomposite as polymeric membranes for water purification. Over the last few years, researchers have demonstrated that adsorbent nanocomposite polymeric membranes are powerful, important, and potential instruments in separation or removal of pollutants, such as heavy metals, dyes, and other toxic compounds presented in water systems. Lastly, we conclude this review with a summary of the most important applications of chitosan-based nanocomposite polymeric membranes and their perspectives in water purification.

“…The selectivity toward As (III) in the consortium of metal ions was improved by doping iron into chitosan nanofibers which increased the specific surface area and thereby exposed more number of potential active adsorption sites on the adsorbent platform. The presence of CN(CC) groups on the adsorbent surface is found to be involved in As(III) removal . Therefore, co‐ordinating iron(III) on amine functionalized poly(glycidyl methacrylate)‐grafted cellulose nanofibers increased the removal efficiency of As(III) ions from aqueous solution by ≈60% (78.8 mg g −1 ).…”

Studies involving bio‐based nanofibers are well utilized in the field of energy, catalysis, electronics, and environmental science. In this review, the importance of utilizing bio‐based materials for the development and optimization of multiplexed nanofibers and the modifications adopted to overcome the drawbacks of conventional electro‐spinning to facilitate better production rates, enhanced adsorption, and its potential in removing heavy metal ions, dyes, and other contaminants polluting the environment are highlighted. This work provides the readers the ability to understand the complexity in fabrication of bio‐based nanofibers focusing primarily on chitosan, cellulose, and protein‐based nanofibers and their mechanism toward quenching/degradation of water contaminants. In addition, it also provides the advantages of using bio‐based materials over synthetic materials for the development of nanofibers.

“…Chitosan (Cs) is derived from chitin as a basic element of D- glucosamine and can be extracted successfully from shellfish [48, 49]. In this work, green PVA/Cs electrospun nanofibrous membranes are designed and their properties including thermal stability, surface area, and size distribution are optimized using multiobjective optimization based on response surface and desirability function analyses.…”
