Heavy metals enter our environment through diverse resources, causing harmful effects owing to their inherent toxicity and facile migration into aqueous medium, becoming an environmental challenge. Among technologies able remove these contaminants, the adsorption process emerges as a promising application for water treatment. Herein, functionalized silica magnetic nanoparticles using inorganic organic have been employed adsorbents hazards from wastewater effectively. Magnetic silicate core-shell amino-functionalized (Fe3O4@SiO2-AP) nanocomposites were synthesised acrylic acid (AA) para-aminobenzoic (PABA) dual copolymer Cd (II) removal. The characterization analysis confirmed formed crystal nanostructure copolymers chemically introduced in nanoparticle. results on achieved impressive qmax of 32.50 mg/g at pH 8, adsorbent dosage 3 g/L, concentration 100 ppm. laboratory-scale fixed-bed column showed breakthrough curves are flow rate independent, achieving metal removal 99% 405 min, influent ion ppm, 5 mL/min, 1 cm bed height. Freundlich model was most suitable fitting equilibrium data (R2adj = 0.981) indicating multi-layer phenomenon heterogeneous surface sites nanocomposites. pseudo-second-order =0.999) confirms that depends active occurs by chemical sorption mechanism. reusability adsorption-desorption experiments slightly decreased 97.5% 86.7% sixth cycle stability, demonstrating material stability.
