Toxic crystal violet dye removal by novel, eco-friendly seablite biochar-ferrite composite: adsorption isotherm, kinetics, and artificial neural network.

ABSTRACT: Rising water demand has intensified pollution and created an urgent need for efficient treatment methods. Adsorption is a green and low-cost approach, yet conventional adsorbents often face sustainability and regeneration challenges. In this study, a novel adsorbent was developed by pyrolyzing Suaeda monoica leaf powder (LP) into biochar (BC300), followed by base treatment and coprecipitation with NiCuZnFe₂O₄ spinel to form a ferrite-biochar composite (FCOB). FCOB effectively removed Crystal Violet (CV) dye from aqueous solution. FE-SEM images revealed a layered morphology, while FTIR analysis confirmed multiple adsorption mechanisms, including hydrogen bonding, electrostatic attraction, surface complexation, and pore filling for CV adsorption.
