ABSTRACT Biodegradable polymeric membranes can reduce the environmental impact of polymer waste from discarded used in water treatment and desalination. Poly(ε‐caprolactone) (PCL), a promising biodegradable material, faces limitations due to its hydrophobicity, affecting salt contaminant adsorption. To overcome this, PCL was blended with oligomeric PCL‐diol (PCL‐D) ratios 90:10, 80:20, 70:30. Additionally, 12 wt% laponite (Lap), an anionic synthetic clay, incorporated enhance mechanical strength functionality. The addition PCL‐D improved porosity, hydrophilicity, antifouling properties, while Lap enhanced performance. pure flux (PWF) increased ~188 Lm −2 h −1 for neat 1124 70:30 blend (P7D3‐L12), contact angle (WCA) decreased ~96° ~49°. P7D3‐L12 membrane exhibited excellent adsorption heavy metals (Pb 2+ ~84.9 Cd ~90.6 mg/g) dyes (MB ~45 NR ~57 mg/g). It also showed ~36%–40% retention after multiple cycles fouling recovery rate (FRR) ~82% five cycles. demonstrated 78% weight loss compost over 54 days, indicating biodegradability. These modified offer solution sustainable treatment.

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
