In this study, the Fe2O3@SiO2-L-cysteine-cellulose system was synthesized and characterized through XRD, FT-IR, EDS, TGA-DTA analyses. This system's adsorption performance evaluated for removing heavy metals such as Cr, Cd, Ni, Pb from synthetic wastewater. The magnetic core demonstrated a beneficial effect on enhancing metal capacity of polymer, while properties facilitated recyclability adsorbent. Cr(VI), Cd(II), Ni(II), Pb(II) ions explored under varying conditions pH, temperature, ion concentration, adsorbent dosage. Maximum capacities were recorded at 423.56 mg/g, 426.32 422.21 respectively, optimal pH 6.5, concentration 600 mg/L, an dose 0.07 g, room temperature. Additionally, material water, N2, CO2 assessed. exhibited excellent removal efficiency Cr(VI) (˃98%) initial 90 mg/L using g combination Fe2O3@SiO2, L-cysteine, cellulose in one performs distinct advantages enhanced surface area adsorbent, preventing degradation harsh conditions, separation reusability

Abstract In this work, the magnetic cellulose acetate butyrate beads (mCABs) were prepared and then, their surfaces modified with [(3‐Aminopropyl) triethoxysilane)] (APTES) solution to generate amine groups (−NH 2 ) as a ligand for DNA adsorption in aqueous solution. After surface modification, −NH functionalized mCABs (N−mCABs) characterized Fourier Transform Infrared Spectroscopy (FTIR), scanning electron microscope (SEM), energy dispersive X‐ray (EDX) analysis. The optimum pH value of was observed at 4 point, N−mCABs adsorbed 4.27 mg/g room temperature (RT). maximum amount calculated 5.24 exothermic; furthermore, monolayer Langmuir model more fitted than Freunclich isotherm due regression coefficient (R ), qmax values model. According reusability studies, adsorbent protected its stability capacity after 5 consecutive adsorption, desorption, regeneration cycles.
