Rapid urbanization and industrial development worldwide have significantly increased the release and spread of anthropogenic heavy metals, extending their impact from local sources to broader regions. This growing pollution poses serious risks to human health and aquatic ecosystems. Although extensive research has been conducted on the removal of heavy metal from water, existing treatment methods still require optimization for improved efficiency and specificity. Among these, adsorption is recognized as the most effective technique, with bimetallic metal-organic frameworks (BMOFs) emerging as highly promising adsorbents due to their exceptional adsorption capabilities and potential to address complex environmental challenges. Therefore, it is essential to implement measures that reduce heavy metal concentrations in water to safe levels. This review provides a detailed account of the sources and toxicity of heavy metals to humans and ecosystems. It explains BMOFs, their synthesis, and mechanisms of interaction with heavy metals, and, for the first time, explores the application of BMOFs for the removal of heavy metals from aqueous environments. In summary, this review offers a comprehensive overview of the latest progress in BMOF-based heavy metal remediation, providing valuable insights for future BMOF synthesis and practical solutions for water decontamination.
