“…The selection of adsorbent components, namely hemicellulose, lignin, alginate, and cellulose, was based on the inherent composition of vegetal material. The choice aligns with the typical constituents found in olive waste, as documented in previous studies [62][63][64]. Given our laboratory-focused objectives, an in-depth chemical composition analysis of the vegetal material was not pursued.…”

This study investigates the efficacy of adsorbents from locally sourced olive waste—encompassing olive skins, leaves, and pits, recovered from the initial centrifugation of olives (OWP)—and a composite with sodium alginate (OWPSA) for the removal of Cu2+ ions from synthetic wastewater. Experimental analyses conducted at room temperature, with an initial Cu2+ concentration of 50 mg/L and a solid/liquid ratio of 1 g/L, showed that the removal efficiencies were approximately 79.54% and 94.54% for OWP and OWPSA, respectively, highlighting the positive impact of alginate on adsorption capacity. Utilizing statistical physics isotherm models, particularly the single-layer model coupled to real gas (SLMRG), allowed us to robustly fit the experimental data, providing insights into the adsorption mechanisms. Thermodynamic parameters affirmed the spontaneity and endothermic nature of the processes. Adsorption kinetics were interpreted effectively using the pseudo-second-order (PSO) model. Molecular modeling investigations, including the conductor-like screening model for real solvents (COSMO-RS), density functional theory (DFT), and atom-in-molecule (AIM) analysis, unveiled intricate molecular interactions among the adsorbent components—cellulose, hemicellulose, lignin, and alginate—and the pollutant Cu2+, confirming their physically interactive nature. These findings emphasize the synergistic application of experimental and theoretical approaches, providing a comprehensive understanding of copper adsorption dynamics at the molecular level. This methodology holds promise for unraveling intricate processes across various adsorbent materials in wastewater treatment applications.

“…Some derivatives of cellulose that are used for the synthesis of cellulose-based hydrogels include esters, ethers, and composites (IPN or polymeric blendings). Gels derived from cellulose derivatives have been shown to be effective adsorbents for various contaminants [78][79][80][81], some of them being dyes (Table 3). Updated literature from the last decade indicated that CS and its derivatives (carboxymethylcellulose, hydroxypropylcellulose) grafted and cross-linked with various reagents (acrylic acid, 2-acrylamido-propanesulphonic acid, itaconic acid, polyacrylic acid) afforded the obtaining of new polymers having good dye adsorption properties.…”

Removal of contaminants from discharge water is vital and demands urgent assistance with the goal to keep clean water. Adsorption is one of the most common, efficient, and low-priced methods used in water treatment. Various polysaccharide-based gels have been used as efficient dye adsorbents from wastewater. This review summarizes cutting-edge research of the last decade of different hydrogels based on natural polysaccharides (chitin, chitosan, cellulose, starch, pullulan, and dextran) concerning their dye adsorption efficiency. Beyond their natural abundance, attributes of polysaccharides such as biocompatibility, biodegradability, and low cost make them not only efficient, but also environmentally sustainable candidates for water purification. The synthesis and dye removal performance together with the effect of diverse factors on gels retaining ability, kinetic, and isotherm models encountered in adsorption studies, are introduced. Thermodynamic parameters, sorbent recycling capacity along with conclusions and future prospects are also presented.

“…Uma das aplicações potenciais dos hidrogéis de celulose bacteriana é a possibilidade de utilizar como suporte para células 3D, com viabilidade do hidrogel intacta após 14 dias de cultura. Porém, há algumas limitações como digestão mediada apenas por celulase, que requer incubação por 24h em temperatura de 37°C e as enzimas residuais apresentam contaminação com resultados inconclusivos (Bhattacharya et al, 2012;Kopjar et al, 2020;Treesuppharat et al, 2017;Radoor et al, 2024;Drury & Mooney, 2003).…”
