Comprehensive analytical review of heavy metal removal efficiency using agricultural solid waste-based bionanocomposites

Heavy metals (HMs) have attracted considerable attention lately because of their widespread occurrence in aquatic environments and potential biological toxicity to animals and humans. The development of economical, efficient, and engineerable adsorbents such as agricultural solid waste-based bionanocomposites (ASWBNCs) for removing HMs from water by adsorption has become a research focus. The review systematically explores the synthesis methodologies of these nanocomposites, emphasizing the utilization of agricultural residues and their conversion into efficient adsorbents. The structural characteristics, including morphology and composition, are discussed, shedding light on the factors influencing the adsorption performance. The mechanisms governing the adsorption of HMs onto ASWBNCs are elucidated, providing insights into the fundamental processes at play. Furthermore, the review evaluates the impact of various parameters, such as pH, temperature, and initial metal concentration, on adsorption efficiency. This review would contribute to preparing engineerable ASWBNCs for HMs removal and provide a roadmap for researchers and others involved with remediating HMs-affected water.
