Water pollution is a global issue because of potentially lethal toxins. Polymeric nanomaterials are making their way into water treatment processes and are being utilized to efficiently remove a variety of pollutants. Polymeric nanomaterials are a popular option for a solution because they have a high adsorption capacity and a high surface charge. Nanocomposites have recently come to the attention of those working in the field of water treatment in order to more effectively remove contaminants. Polymeric composites are based on biopolymers and are being developed. These all quickly reached the industrial standards because of their low impact on the natural world. Chitosan is one of the biopolymers that are used extensively. Moreover, it is one of the most highly preferred biopolymers. It is simple to scale up and is readily available. The incorporation of nanomaterials into the biopolymer enables better control over the shape, size, and morphology of the particle, as well as an increase in the efficiency with which contaminants are removed. This is an excellent review that examines recent developments in the formation of chitosan-based polymeric nanocomposites and their performance in removing various contaminants including heavy metals, dyes, pesticides, pharmaceutical waste, and radionuclides from water.

Effect of Starch and Chitosan Addition on Swelling Properties of Neutralized Poly(Acrylic Acid)-Based Superabsorbent Hydrogels Prepared by Using γ-Irradiation Technique

Superabsorbent hydrogels are polymers with a 3D network that have attracted the attention of scientists and industrialists because of their fantastic ability to absorb and retain water and aqueous solutions. The most widely used and commercially available superabsorbent hydrogels are synthetic K-acrylate materials. In this novel study, superabsorbent hydrogels have been developed using natural ingredients to have more biodegradable properties. Superabsorbent hydrogels were synthesized from acrylic acid, cassava starch, and chitosan using the γ-irradiation method under different experimental conditions. The γ-irradiation technique was chosen to produce hydrogels free of residues that may remain when chemical crosslinkers are used. The effects of irradiation dose, acrylic acid composition, and the amount of cassava starch and chitosan on the characteristics of produced hydrogels were analyzed. The resulting polymers were further characterized by fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) to evaluate the structure. The thermal behavior of superabsorbent products at different neutralization doses was tested with differential scanning calorimetry (DSC). FTIR data indicated that the grafting reaction was successfully implemented in this work. SEM analysis showed that the hydrogel produced from this study was porous and there was a reduction in pore size with the addition of starch and chitosan. It can be concluded that the addition of cassava starch and chitosan affects the acrylic acid-based superabsorbent properties, which are pore size, thermal behavior, gel content, antibacterial activity, and swelling capacity in water, salt, and urea solutions. The best hydrogel was obtained by adding 0.25 g of cassava starch and 0.25 g of chitosan, using 50 % acrylic acid neutralization and 5 kGy γ-irradiation doses. The graft polymers possess the maximum swelling capacity of 670 g/g for distilled water, 520 g/g for NaCl solution, and 767 g/g for urea solution (relative to the dry weight). These products were sterile from Escherichia coli bacteria and had the potential to be applied as superabsorbent resins for various fields.

“…Unfortunately, these technologies' generality is expensive and/ or environmentally unfriendly. Adsorption has been popular as a method for eliminating radionuclides because of its many bene ts, including high e ciency, environmental friendliness, and low cost [10,[14][15][16][17]. The goal of this research is to develop and test a low-cost starch-grafted poly(acrylic acid-vinylsulfonic acid) (St-g-PAA-PVSA) graft co polymer for removing Co(II) and Eu(III) from radioactive waste under various experimental settings.…”

Graft copolymer of starch-polyacrylic acid-polyvinylsulfonic acid (St-g-PAA-PVSA) was synthesized by gamma radiation as an initiator. The chemical structure, morphology, and thermal stability of the graft copolymer were investigated using FTIR, SEM, and TGA. St-g-PAA-PVSA graft copolymer was employed as an adsorbent for the removal of cobalt(II) and europium(III) radionuclides from their aqueous solutions by batch adsorption method. Several experimental factors such as pH, contact time, initial concentration of adsorbate, and temperature were used to find the best conditions for the removal of cobalt(II) and europium(III) radionuclides. The pseudo-second order kinetic model better fit the adsorption kinetic data of radionuclides. Langmuir models had the ability to well describe the equilibrium data of adsorption of radionuclides. Thermodynamic parameters were calculated and suggested the adsorption process was endothermic and spontaneous in nature. Among the examined desorbing agents, both AlCl3 and HCl were succeeded to desorb most of radionuclides.
