The increasing contamination of water by various heavy metals has emerged as a pressing global issue, threatening human health, aquatic ecosystems, and agricultural sustainability. These heavy metals are required to remove through cost effective and efficient removal approaches due to their toxicity, persistence and bioaccumulation. This review explores the transformative potential of nanocomposites as advanced adsorbents for heavy metal elimination. By investigating their synthesis, characterization, and functional classifications, the study highlights how these materials outperform conventional methods through enhanced surface properties and adsorption efficiency. A comparative analysis of adsorption mechanisms, such as ion exchange, electrostatic interactions, and complexation, is addressed, alongside evaluations of critical operational parameters like pH, contact time, and percentage removal. Additionally, the paper also outlines the limitations of current nanocomposite technologies, such as scalability challenges and environmental concerns, while potential future options for the removal of heavy metals. This review sets the groundwork for future nanomaterials developed to address global water decontamination by extending knowledge in this field.
