Introduction: Currently, Cadmium (Cd2+) contamination in plant-based proteins is a significant food safety challenge that is not effectively treated by classical processing methods. Thus, the development of selective, efficient, and sustainable strategies for its remediation is essential to ensure compliance with regulatory standards and protect consumer health. Methods: EDTA-functionalized silica gel (EDTA@SiO2) sorbent was synthesized via silanization and EDTA grafting and characterized using FTIR, XRD, SEM, DLS, and zeta potential analysis. Optimization of adsorption conditions was carried out through Plackett–Burman design and response surface methodology, and selectivity and reusability were also evaluated. Results: Maximum adsorption efficiency was observed at pH 4.5, resulting in >99% Cd2+ removal from pea protein slurries. The Cd2+ concentration was reduced to 0.04 mg/kg. The sorbent retained >98% of its efficiency after five adsorption-desorption cycles. Discussion: The developed sorbent demonstrated excellent selectivity for Cd2+ in the presence of essential ions (Ca²⁺, Mg²⁺, Zn²⁺, K⁺), maintaining the nutritional quality of the supplement. Its high reusability proves its economic feasibility and suitability for repetitive use in industrial applications. Conclusion: The developed EDTA@SiO2 sorbent is an effective, selective, and reusable material for Cd2+ remediation, offering a practical and sustainable solution to enhance food safety in plant protein production.
