Excessive Zn(II) ions in aquatic environments pose significant risks to both human health and ecological systems due their toxic effects, bioaccumulation potential, interference with essential biological processes. To address this issue, a novel analcime@calcium aluminate@polyethylene glycol 400 (ACP) nanocomposite was fabricated using the hydrothermal technique, alongside an aluminate (AC) for efficient elimination of from aqueous media. X-ray diffraction (XRD) analysis affirmed successful formation crystalline phases, revealing average crystallite sizes 72.93 nm AC 63.60 ACP. Energy-dispersive spectroscopy (EDX) confirmed elemental composition nanocomposites, showing that primarily contained oxygen, sodium, aluminum, silicon, calcium, whereas ACP incorporated 19.3% carbon polyethylene 400. Field emission scanning electron microscopy (FE-SEM) revealed exhibited hexagonal platelet-like structures, displayed more dispersed layered morphologies. High-resolution transmission (HR-TEM) presence stacked structures defined, separated nanosheets The maximum adsorption capacities were 149.93 230.95 mg/g, respectively. pathway onto involved three primary interactions: electrostatic attraction facilitated by calcium aluminate, ion exchange provided analcime, complexation promoted Thermodynamic indicated process exothermic, spontaneous, chemical nature. Kinetic modeling followed pseudo-second-order model, while isotherm studies demonstrated adherence Langmuir indicating monolayer on homogeneous sites.
