摘要

The use of agrifood waste-based adsorbents for removing pesticides from contaminated water represents a promising and sustainable approach to address growing environmental and public health concerns. This review provides a comprehensive analysis of the capabilities of agrifood waste-derived materials in pesticide remediation, with a particular focus on surface modifications, structure–function relationships, and the mechanisms governing adsorption. Key factors influencing adsorption efficiency, such as pesticide type and concentration, pH, contact time, temperature, and adsorbent characteristics, are critically examined. Moreover, emerging technologies, including physical and chemical modification methods, electrospinning, and nanostructuring, are explored for their potential to enhance adsorbent surface area, porosity, and functional group availability. In addition, advanced data-driven approaches based on artificial intelligence and machine learning are discussed as tools for optimizing adsorption processes and predicting performance under complex, multicontaminant conditions. Despite technological progress, key challenges remain, including economic cost, limited regenerability, and reusability of bioadsorbents, as well as competing uses of agrifood residues in other valorization pathways. Understanding competitive adsorption mechanisms and ensuring scalability in real-world applications remain key priorities. By integrating technological innovations with sustainability considerations, this work provides a forward-looking perspective on scaling agrifood waste-based adsorbents for environmental remediation applications.
