This study addresses the critical issue of removing copper(II) ions from water using an eco-friendly approach with natural biomaterials. Alginate, a polysaccharide, is employed as primary adsorption material. The involves conversion alginate into nanoparticles, and ternary blend prepared by mixing nanoparticles carboxymethyl cellulose polyethylene glycol (AL-NPs/CMC/PEG). blend's morphological structural transformations have been comprehensively investigated techniques such DLS, FT-IR, XRD, TGA, SEM. Batch experiments were conducted systematically to investigate crucial parameters, contact time (60–300 min), initial copper concentration (62.5 ppm–1000 ppm), solution pH (2–8), adsorbent dosage (1–5 g). results obtained are highly encouraging, revealing impressive 80.9 % efficiency in removal ions. acquired experimental data then subjected analysis Langmuir Freundlich, isotherm, well pseudo-first pseudo-second-order kinetics studies. outcomes these isotherm models indicated favorable fit Freundlich suggesting strong affinity between metal Furthermore, kinetic studies revealed that process closely adheres kinetics, underlining reliability process. From desorption studies, 0.1 M HCl was extremely effective eluant when compared HNO3 EDTA. It could be reused three appreciate efficiency. research underscores potential for environmentally sustainable address persistent environmental challenge posed ion contamination.
