Cement-based foam composites have gained attention as innovative and high-performing adsorbents for wastewater treatment due to their lightweight, porous, structurally robust properties. This study investigates the adsorption of Eriochrome Black T dye onto biochar-modified cement foam, providing a cost-effective solution industrial management. The integration biochar into enhances its surface area capabilities while maintaining structural stability tunable porosity. were characterized using scanning electron microscopy, Fourier-transform infrared spectroscopy, energy-dispersive X-ray spectroscopy verify quality functionality. process adhered Freundlich isotherm model (R2 = 0.967), indicating multilayer adsorption, with maximum capacity 13.33 mg/g under optimal conditions.
