Abstract
The intensifying problem of heavy metal contamination in water sources has led to the need for efficient and sustainable remediation technologies. Biomass-based adsorbents have emerged as a promising solution due to their cost-effectiveness, renewability, and environmental advantages. This review thoroughly analyzes recent advancements in biomass-based adsorbents for heavy metal remediation. It evaluates different types of biomass materials, such as agricultural residues, forestry by-products, and aquatic plants, highlighting their adsorptive capacities, modification techniques, and operational efficiencies. The review also explores the mechanisms of metal uptake, such as ion exchange, adsorption, and complexation, and discusses the performance of different biomass adsorbents. Furthermore, it highlights the key challenges and limitations associated with biomass-based adsorbents, such as regeneration issues, stability concerns, and scalability. By consolidating current research and technological developments, this review aims to offer insights into optimizing biomass-based adsorbents for practical applications and outlining future research directions in heavy metal remediation.
