Considering the circular economy and environmental protection, sustainable recovery of high-value metals from wastewater has become a prominent concern. Unlike conventional methods featuring extensive chemicals or energy consumption, membrane separation technology plays a crucial role in facilitating the sustainable and efficient recovery of valuable metals from wastewater due to its attractive features. In this review, we first briefly summarize the sustainable supply chain and significance of sustainable recovery of aqueous high-value metals. Then, we review the most recent advances and application potential in promising state-of-the-art membrane-based technologies for recovery of high-value metals (silver, gold, rhenium, platinum, ruthenium, palladium, iridium, osmium, and rhodium) from wastewater effluents. In particular, pressure-based membranes, liquid membranes, membrane distillation, forward osmosis, electrodialysis and membrane-based hybrid technologies and their mechanism of high-value metal recovery is thoroughly discussed. Then, engineering application and economic sustainability are also discussed for membrane-based high-value metal recovery. The review finally concludes with a critical and insightful overview of the techno-economic viability and future research direction of membrane technologies for efficient high-value metal recovery from wastewater.
考虑到循环经济和环境保护，从废水中可持续地回收高价值金属已成为一个突出的关注点。与传统方法相比，膜分离技术因其具有吸引力的特点，在促进从废水中可持续和高效地回收有价值的金属方面发挥着至关重要的作用。在本文综述中，我们首先简要总结了可持续供应链和从废水中可持续回收高价值金属的意义。然后，我们综述了最新的进展和有前途的基于膜的先进技术在从废水废水中回收高价值金属（银、金、铼、铂、钌、钯、铱、锇和铑）方面的应用潜力。特别地，我们深入讨论了基于压力的膜、液膜、膜蒸馏、正向渗透、电渗析和基于膜的混合技术及其回收高价值金属的机制。然后，还讨论了基于膜的高价值金属回收的工程应用和经济可持续性。最后，本文对膜技术从废水中高效回收高价值金属的技术经济可行性和未来研究方向进行了批判性和有见地的概述。
