Background: Water contamination by noxious heavy metals due to urbanization is a global environmental problem. Heavy metal ions pollution makes the water unsuitable for drinking and is also highly toxic to human beings and eco-system. The remediation of heavy metals is therefore very crucial.

Methods: Adsorbents based on biopolymer and eco-friendly polymer composites have been developed and fabricated to remediate and remove heavy metals from the ecosystem.

Results: In recent years, biocomposites have been successful as cost-effective adsorbents for the remediation of various contaminants with their eco-friendly nature and sustainability.

Conclusion: This review article gives an overview on the remediation of heavy metals using green biocomposites.

背景：城市化造成的有毒重金属污染水是一个全球性的环境问题。重金属离子污染使水不适合饮用，对人类和生态系统也有剧毒。因此，重金属的修复非常重要。

方法：已经开发和制造了基于生物聚合物和环保聚合物复合材料的吸附剂，以修复和去除生态系统中的重金属。

结果：近年来，生物复合材料因其生态友好性和可持续性，已成功成为修复各种污染物的具有成本效益的吸附剂。

结论：这篇综述文章概述了使用绿色生物复合材料修复重金属。
