Innovative eco-friendly methyl orange removal: Mechanism, kinetic, and thermodynamic study using starch cryogel-integrated mesoporous silica nanoparticles.

ABSTRACT: This study introduces a novel, eco-friendly composite, uncalcined mesoporous silica nanoparticles incorporated into a starch cryogel (MSNs-Cry), designed for the effective removal of methyl orange (MO) from water. MSNs-Cry integrates uncalcined mesoporous silica nanoparticles (MSNs) within a starch cryogel network, leveraging the high adsorption capacity of MSNs. The composite achieved a maximum adsorption capacity of 18.98 mg g⁻¹ and demonstrated high removal efficiencies of 99.00 % ± 0.21 % in synthetic water (10 mg L^-1 MO) and 92.77 % ± 1.76 % in real wastewater containing 0.43 mg L^-1 MO. The Langmuir isotherm model provided a superior fit (R² = 0.9930) compared to the Freundlich model (R² = 0.9180), and the adsorption kinetics foll
