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.

In the present study, a novel superparamagnetic nanocomposite composed of magnetite as the core and zeolite coated by glutaraldehyde-crosslinked chitosan as the shell has been successfully synthesized. The synthesis steps include coating silica on the surface of magnetite nanoparticles and conversion of the silica layer into a zeolite layer, coating of chitosan on the surface of the zeolite, and cross-linking reaction of chitosan using glutaraldehyde. The X-ray diffractogram has proven that the magnetite nanoparticles formed on the nanocomposite have a cubic structure. The formation of the minerals mordenite, clinoptilolite, and quartz on the magnetite surface is also confirmed. Infrared spectral analysis has revealed the existence of Fe-O-Si and Fe-O-Al bonds between magnetite and zeolite, and C=N bonds between chitosan and glutaraldehyde. The TEM image clearly shows that the resulting nanocomposite consists of zeolite-coated magnetite nanoparticles, which are incorporated in a glutaraldehyde crosslinked chitosan gel system. Measurements with ImageJ software suggest that the diameter of the composite is in the range of 20-75 nm, with an average diameter of 34.06 nm. Magnetic studies indicate that the nanocomposite is superparamagnetic with a saturation magnetization of 27.5 emu/g. Since the magnetite nanoparticles is positioned in the core of the composite, it is well protected from oxidation and therefore it is expected to have high magnetic stability. This magnetically separable nanocomposite is quite interesting and may be applied in the adsorption of heavy metal ions and cationic dyes from aquatic medium.

“…Unfortunately, heavy metals are constantly being released into the environment from anthropogenic sources: metalliferous mining and smelting (As, Cd, Pb, Hg), industry (As, Cd, Cr, Co, Cu, Hg, Ni, Zn), atmospheric deposition (As, Cd, Cr, Cu, Pb, Hg, U), agriculture (As, Cd, Cu, Pb, Si, U, Zn) and waste disposal (As, Cd, Cr, Cu, Pb, Hg, Zn). [1][2][3] Consequently, the amounts of heavy metals deposited on the Earth's surface are considerably higher compared to natural background concentrations. Heavy metals accumulate over time and since they are non-decomposable or non-biodegradable, they are the long-term health and environmental hazards.…”

Polymer-based, highly porous nanocomposites with functionalized ligands attached to the core structure are extremely efficient in the detection, removal and recovery of metals through the process of sorption. Quantumchemical models could be helpful for sorption process analyses. The sorption of Cu(II) ions by amino-functionalized chelating macroporous copolymers poly(GMA-co-EGDMA)-amine and sorption selectivity of the subject copolymers, ethylenediamine (en), diethylenetriamine (dien) and triethylenetetramine (trien), were successfully modelled by quantum chemical calculations. Considering the crystal structures from CSD and experimental conditions during the formation of metal complexes, the most frequent mononuclear complexes are those with the tetradentate teta ligand, while binuclear complexes are formed when the metal ion is in large excess. Although the en-copolymer was the most effective functionalized one, higher maximum sorption capacities (Qmax) were observed for the dien- and trien-copolymers, due to their abilities to form binuclear complexes. The enthalpy term has the greatest contribution to the total Gibbs energy change of reaction for the formation of mononuclear Cu(II) complexes (?Gaq), while the solvation energy of the reaction has the greatest contribution in the formation of binuclear complexes. The results of the study indicate that small amines with the ability to form binuclear complex are the best choice for functionalization of the considered copolymer.
