重金属离子污染对人类健康造成严重威胁。为此，设计并制备了一种天然高效的海藻酸钠(ALG)/聚乙烯亚胺(PEI)复合水凝胶用于废水中重金属离子的去除。本文对ALG基三维复合水凝胶对重金属离子的吸附进行了深入的研究。此外，原位还原金属纳米粒子负载的ALG/PEI复合水凝胶为重金属离子的可持续利用提供了一条具有良好的吸附催化能力的途径。总体而言，本研究将为废水中重金属离子的级联处理和回收提供一种有效和实用的范式。
Heavy metal ion pollution leads to severe health risk to human beings. Herein, a natural and highly efficient sodium alginate (ALG)/polyethyleneimine (PEI) composite hydrogel was designed and fabricated for the removal of heavy metal ions from wastewater. The adsorption of heavy metal ions on the ALG based, 3D composite hydrogel were thoroughly investigated in this study. Furthermore, the in situ reduced metal nanoparticle-loaded ALG/PEI composite hydrogel provided us a sustainable utilization route of the heavy metal ion with a promising adsorption-catalysis ability. In general, this research will present an effective and practical paradigm for the cascaded treatment and recycling of heavy metal ions in wastewater.
