Summary: In this study, torrefied wheat straw and oat hulls were combined with kaolinite and chitosan to obtain pelletized adsorbent materials. The composites were compared to spent coffee grounds as a reference biomass system. IR and C-13 NMR spectroscopy were used for structural characterization, and a cationic dye probe was employed to evaluate the adsorption properties. The results showed that crosslinking notably reduced the adsorption capacity for torrefied biomass composites, while greater uptake occurred for the spent coffee grounds composites. A cost-benefit analysis indicated that the torrefied wheat straw composites are competitive adsorbents per dollar material cost compared to the spent coffee grounds composites. Pelletized adsorbent technology with torrefied biomass offers lower chemical input costs and sustainability.

Summary: In this study, a novel hybrid multifunctional biocomposite of chitosan grafted-benzaldehyde/montmorillonite/algae (CHS-BZ/MT/AL) was designed and applied for highly efficient removal of brilliant green (BG) and reac-tive blue 19 (RB19) dyes from water. The effects of CHS-BZ/MT/AL dose, pH solution, and contact time on the removal rate of BG and RB19 dyes were investigated using response surface methodology. The experimental results showed that CHS-BZ/MT/AL had a maximum adsorption capacity of 899.5 mg/g for BG and 213.6 mg/g for RB19.

Summary: In this study, a simple one-pot solvothermal approach has been used to create magnetic porous carbon nanocomposites obtained from a nickel-based metal-organic framework (Ni-MOF) for the adsorption of methyl orange (MO) dye. The derived carbons, known as CDM-700, CDM-800, and CDM-900, exhibited exceptional porosity and magnetic properties when pyrolyzed at different temperatures under a nitrogen atmosphere. Various analysis methods were employed to characterize the prepared powders. The maximum adsorption capacities of Ni-MOF, CDM-700, CDM-800, and CDM-900 for MO dye were found to be 307.38, 5976.35, 4992.39, and 2636.54 mg/g, respectively. The synthesized nanocomposite showed promising potential as a superadsorbent for dye removal from contaminated water.

Summary: In this study, eggshell powder (ESP) was used as a selective heterogeneous catalyst for the oxidative degradation of crystal violet (CV) dye in aqueous media. ESP acted as a carbonate (CO32) source, facilitating the formation of carbonate anion radicals (CO3 (center dot-)) in the presence of H2O2. The combination of these radicals and center dot OH radicals led to the selective degradation of CV dye. The use of ESP as a catalyst offers a promising route for CV degradation and the utilization of eggshell waste.

Summary: In this study, poly(maleic acid)-grafted cross-linked chitosan/montmorillonite composite nanospheres (PMAL-CTS/MMT) were synthesized for efficient adsorption of organic dyes. The high adsorption capacity of PMAL-CTS/MMT towards both anionic and cationic dyes can be attributed to the presence of abundant functional groups. The surface charges of PMAL-CTS/MMT can be modulated by adjusting the solution pH, resulting in enhanced affinity towards different types of dyes. The proposed adsorption mechanism involves electrostatic interaction, pi - pi interactions, and hydrogen bonding. Additionally, PMAL-CTS/MMT was successfully utilized for the separation of dyes from real-life aquatic environments.

Summary: In this study, microalgae (MAG) was used as an environmentally friendly and efficient adsorbent for the removal of crystal violet (CV) and methylene blue (MB) dyes from aqueous solutions. The adsorption process was optimized using a Box-Behnken design (BBD), and the kinetics and isotherm analyses revealed that the adsorption followed the pseudo-second-order and Langmuir models. MAG exhibited a maximum adsorption capacity of 243.0 mg/g for CV and 297.1 mg/g for MB. The thermodynamic parameters indicated that the adsorption of CV and MB dyes onto MAG was spontaneous and endothermic. The adsorption mechanism involved electrostatic forces, n-?? stacking, and H-bonding. Overall, MAG shows promise as an effective adsorbent for removing dyestuffs from industrial effluent.

Summary: This study proposed the development of a nanoscale adsorbent material using waste from Moringa oleifera seeds for the removal of Indigo Carmine from textile effluents. The adsorption process was found to fit the Langmuir isotherm in the equilibrium of adsorption and the power function in the kinetic behavior. The maximum adsorption capacity of the absorbent nanoparticles was significantly higher than that of the bulk Moringa oleifera seeds. The dominant mechanisms of Indigo Carmine adsorption on the nanoparticles were identified as hydrogen bonding, electrostatic interlinkage, and pi-pi interactions. The Moringa oleifera seed nanoparticles showed promise as a green and low-cost adsorbent for textile wastewaters.

Summary: In this study, chitosan-coated clinoptilolite zeolite was investigated as an adsorbent for the removal of methyl violet from aqueous solutions. The adsorbent was characterized and its effectiveness was examined under various parameters. The experimental data showed that the adsorption isotherms followed the Langmuir equilibrium isotherm model equation, and the maximum adsorption capacity was found to be 111.11 mg g(-1) at 318 K. The adsorption of methyl violet was found to conform to the pseudo-second-order kinetic model. A neural network model was developed to predict dye removal, and it was concluded that it could be used effectively. Overall, the developed chitosan coating on clinoptilolite zeolite composite proved to be a natural, cost-efficient, and eco-friendly adsorbent for the removal of methyl violet from aqueous solutions.

Summary: Modification of chitosan through methods such as grafting and cross-linking is a promising approach for removing organic and inorganic pollutants from aqueous medium. The performance of modified chitosan for adsorption of pollutants depends largely on the modification method adopted, materials used, and adsorption experimental conditions. Cross-linking is commonly used for improving the stability of chitosan, although it may decrease adsorption capacity, but recent works have shown enhancement through grafting or incorporation of solid adsorbents before cross-linking.
