To synthesize a clay/carbon composite from spent bleaching earth industrial waste and evaluate its capacity to remove toxic anionic Eosin Y dye from aqueous solution.
Synthesized a clay/carbon composite (SBE/C) via thermal treatment of industrial spent bleaching earth at 700°C under a controlled atmosphere.
Tested Eosin Y adsorption kinetics, equilibrium capacity across varying pH ranges (pH 5–12), and recycling performance, followed by mechanism characterization.
SBE/C exhibited an equilibrium adsorption capacity of 11.15 mg/g, nearly three times greater than raw SBE at 4.04 mg/g.
The adsorption reaction was spontaneous, exothermic, stable across a broad pH range of 5 to 12, and maintained satisfactory recyclability.
Characterization revealed dye uptake occurred via electrostatic interactions, hydrogen bonding, hydrophobic interactions, halogen bonding, and π-π stacking.
