The applicability of Asparagus plant functionalized with iron oxide nanoparticles synthesis for eliminating dyes from aqueous media has been confirmed. The techniques including FT-IR, BET, XRD and SEM for investigation showed the applicability of Asparagus plant functionalized with iron oxide nanoparticles as adsorbent for proper deletion of Methyl Orange dye from aqueous, and article the values of 15 mgL-1, 0.1 g, 7.0, 20.0 min were considered as the ideal values for Methyl Orange dye concentration, adsorbent mass, pH value and contact time respectively. The adsorption equilibrium and kinetic data were fitted with the Langmuir monolayer isotherm model (q: 0.9915) and pseudo-second order kinetics (R2: 0.998) with maximum adsorption capacity (qmax: 167.7 mgg-1) respectively. Thermodynamic parameters (ΔG°: -11.42 kJ mol-1, ΔH°: 33.3 kJ mol-1, ΔS°: 145.8 kJ mol-1 K-1), also indicated Methyl Orange dye adsorption is feasible, spontaneous and endothermic. Overall, taking into account the excellent efficiency, good regeneration and acceptable performance in real terms, Asparagus plant-capped Fe3O4NPs can be introduced as a promising absorbent for dyes removal from aqueous solutions.
