This study developed composite microspheres from orange peel biochar pyrolyzed by 300 °C-900 °C and sodium alginate to address the removal of crystal violet (CV). Biochar was at different temperatures, 800 (B800) based‑sodium (BS800) showed highest adsorption performance, in which, specific surface area pore size B800 387.47 m2/g 1.66 nm, respectively. Adsorption primarily driven chemical mechanisms, as confirmed kinetic isothermal models, while thermodynamic analysis revealed process be spontaneous endothermic. BS800 demonstrated excellent stability with a low CV release risk (<0.6 %) regeneration ability (>85 its efficiency after five cycles. These findings highlight application potential for safe effective food aquatic product processing, offering sustainable solution via utilization agricultural waste.
