ABSTRACT The development of efficient adsorbents with high selectivity is essential for mitigating environmental pollution. This study introduces a novel adsorbent comprising metal–organic framework (i.e., MIL‐101(Fe)‐NH 2 ) and covalent organic (COF) enriched carboxyl groups, which designated /COF‐COOH. synthesized through Schiff base reaction followed by carboxymethylation subsequently employed Pb (II) adsorption. structure /COF‐COOH confirmed using various characterization techniques, including Fourier transform infrared spectroscopy, scanning electron microscopy, X‐ray diffraction, thermogravimetric analysis, Brunauer, Emmett, Teller surface area analysis. adsorption capacity (q e value estimated batch experiments . effects several factors, pH, dosage, contact time, concentration, solution ionic strength, temperature, on the process are systematically assessed. achieves highest 184 mg/g at pH 6. kinetics, isotherms, thermodynamics indicate that occur spontaneous monolayer chemical process. Moreover, displays remarkable anti‐interference capability, its q decreases only 10% after 10 cycles. Based results, mechanism determined to be primarily electrostatic chelation interactions between O‐ N‐containing functional groups. Thus, this highly recyclable exhibits considerable potential removing from aquatic ecosystems.

The rapid pace of global industrialization and population growth has intensified freshwater scarcity water pollution, necessitating urgent solutions. Adsorption technology, favored for its cost-effectiveness, simplicity, scalability, emerged as a promising approach. Hydrogels, particularly cellulose-based hydrogels (CBHs), have gained significant attention green adsorbents due to their biodegradability, non-toxicity, low cost, exceptional adsorption capacity. This paper reviews recent advancements in CBHs sustainable wastewater treatment, focusing on synthesis techniques, performance, mechanisms removing heavy metals, dyes, micropollutants. Updated applications outcomes are also discussed. Despite advantages, face challenges such limited mechanical strength, practical production difficulties, insufficient reuse studies, separation inefficiencies. review addresses these issues explores future prospects implementation. findings provide valuable insights into advancing efficient treatment
