Heavy metal ion pollution in aquatic environments is a critical global issue, damaging ecosystems and threatening human health via bioaccumulation in the food chain. Despite promising progress with biosorbents, the development of environmentally friendly and stable heavy metal adsorbents requires further exploration. In this study, we present an algae-loaded alginate hydrogel as a composite adsorbent for heavy metals. The incorporation of algae enhanced the hydrogel's adsorption capacity by 38.0%, 20.6%, and 27.1% for Cu, Cr, and Co, respectively. Additionally, the composite hydrogel demonstrated excellent stability and recyclability after adsorption, reducing the ecological risks associated with algae biomass usage. This algae-loaded alginate hydrogel offers an efficient and eco-friendly strategy for removing heavy metal ions from aquatic systems, highlighting its potential for environmental remediation applications.
水生环境中的重金属离子污染是一个严峻的全球性问题，它破坏生态系统，并通过食物链中的生物累积威胁人类健康。尽管生物吸附剂取得了有前景的进展，但开发环境友好且稳定的重金属吸附剂仍需进一步探索。在本研究中，我们提出了一种负载藻类的海藻酸盐水凝胶作为重金属复合吸附剂。藻类的加入分别使水凝胶对铜、铬和钴的吸附容量提高了38.0%、20.6%和27.1%。此外，复合水凝胶在吸附后表现出优异的稳定性和可回收性，降低了与藻类生物质使用相关的生态风险。这种负载藻类的海藻酸盐水凝胶为从水生系统中去除重金属离子提供了一种高效且环保的策略，凸显了其在环境修复应用中的潜力。
