Rapid industrialization has led to significant environmental challenges, particularly in wastewater treatment, where the removal of heavy metal ions and organic dyes is critical. This study presents synthesis characterization a high-performance hydrogel adsorbent, (nanoclay)x@poly-γ-glutamic acid (γ-PGA)/polyethyleneimine (PEI) adsorbent (denoted as NxPP, x = 0, 20, 40, 60, 80), for efficient (Cu2+, Fe3+, Zn2+) (Methylene blue, typical example) from wastewater. The was prepared using one-pot method, combining γ-PGA PEI with varying amounts nanoclay. N80PP demonstrated exceptional adsorption capacities, achieving 224.37 mg/g Cu2+, 236.60 151.95 Zn2+ within 30 min, along 88.18 Methylene blue 5 h. incorporation nanoclay significantly enhanced mechanical properties, compressive strength reaching 560.49 kPa. exhibited excellent reusability, maintaining high capacity after five cycles. kinetics followed pseudo-second-order model, isotherms fit Freundlich indicating multilayer mechanism. highlights potential NxPP hydrogels versatile sustainable solution treatment.
