“…Hence, due to the adsorption intensity, a clear and significantly more than a few CV dye was observed among Agg-PAA/AC hydrogel composite. In addition, the hydrogels before the adsorption method with the CV dye illustrated a clear decrease in the IR spectra in the intensity of the bands adjacent to the adsorption [16][17][18]. The surface contains the acidic group that leads to a difference in the intensity of absorption.…”

Dye contamination is a major source of environmental pollution and health dangers practically in each section of the developing world, as people add color to textiles, paper, leather, and other materials to adorn and preserve them. Nowadays, green methods are considered the most important ways to solve environmental problems, especially the problems of the aquatic environment, and they fulfill the requirements of social, environmental, and economic guarantees. A new, environmental-friendly, and stable absorbent material has been prepared with absorbent properties based on biopolymers that have been successfully applied during the polymerization process with free radicals as a superabsorbent Ag-g-PAA/AC hydrogel. Many techniques were used to study the surface properties of the prepared hydrogel, including (FTIR, XRD, and FE-SEM). Several factors that affected the adsorption process were studied, including the effect of dye concentration, effect of hydrogel weight, effect of pH, and surface reactivation. Also, the adsorption isotherms of the Freundlich and Langmuir models were studied. Based on the findings, it was discovered that, depending on the R2 value, adsorption isotherms followed the Freundlich model.

Anthropogenic actions, environmental catastrophes, urbanization, population growth, and industrialization generate toxic pollutants in water bodies. The most pollutants are heavy metals and metalloids, dyes, volatile organic compounds, pharmaceuticals, pesticides, radionuclides, aromatic hydrocarbons, oils, polycyclic aromatic hydrocarbons, microbes/pathogens, and microplastics that can be in different forms and concentrations. [3][4][5] Globally, approximately 2 million tons of pollutants from agriculture, industrial, and sewage waste are released into water streams, which pose severe health risks and cause the deaths of more than 1400 people every day. [6] Thus, developing efficient, economical, environmentalfriendly, and scalable technologies for the purification of wastewater and seawater is urgently required. To fulfill the shortage of clean water, affordable technologies can be used to transform unconventional water reserves (such as wastewater, rainfall, seawater, and brackish water) into potable water. Recently, numerous water treatment technologies, including coagulation/flocculation, filtration, chemical precipitation, aerobic/anaerobic processing, biological treatment, electrochemically precipitation, advanced oxidation processing, membrane separation, ion-exchange, adsorption, solar/thermal distillation/evaporation, crystallization, and photocatalysis, have emerged to offer practical solutions to water pollution management. [7][8][9][10][11][12][13][14] Among them, adsorption and photocatalysis technologies have garnered significant attention from the research community due to their cost-effectiveness, high performance, Hydrogels have been employed for water purification applications, but their performance and strength are unsatisfactory for widespread adoption. Recently, hydrogel nanocomposites have been proposed to resolve the inherent challenges faced by hydrogels for water treatment. This review comprehensively analyzes hydrogel nanocomposites for water treatment using adsorbent and photocatalysis techniques. The structure, classification, and tunable synthesis methods of hydrogels are explained. Further, how hydrogels can be incorporated with functional nanoparticles (NPs) and can be used as templates/precursors for developing advanced 3D architectures, including the formation of hydrogel nanocomposite beads and 3D printing objects are discussed. Finally, the structure-property relationships of hydrogel nanocomposites are critically reviewed by considering introductory gelation chemistry, such as swelling characteristics, mechanical properties, stimuli-responsiveness, and ionic/electronic conduction. The extensive cross-linking of polymer chains with NPs offers high mass/charge transport, high surface areas, and enhanced polymer-water interactions to achieve high-performing adsorbents and photocatalysts. Several motivating examples of emerging NP-containing hydrogel nanocomposites for use in adsorbents and photocatalysis have been discussed. Such efforts validated the excellent technological pote...

Lithium-ion based Solid Polymer Electrolytes are synthesized by incorporating lithium perchlorate (LiClO4) salt with Iota-Carrageenan (IC) / Acacia Gum (AG) plasticized with ethylene glycol (EG) by solution casting method. The X-ray diffraction and Fourier transform infrared analysis are used to analyze the structural and molecular complexation. AC impedance analysis spectra show that the incorporation of 15 wt. % of LiClO4 salt into a blend polymer electrolyte (IAO15) shows the ionic conductivity of 2.02 ×10 -2 S/cm and minimum activation energy (0.022 eV). The conduction mechanism for IAO15 sample follows two models (CBH and QMT). The dielectric and modulus spectra confirm the non-Debye nature of the sample. From the Transference Number Measurement, it is observed that the conductivity is due to Li ions and IAO15 sample is chosen for the fabrication of a Symmetrical 2 supercapacitor. At 3.6 Ag -1 current density, the power and energy densities are noted as 7452 Wkg -1 and 165.6 Whkg -1 respectively.
