Biosorption is a promising technology not only for the removal of heavy metals and dyes but also for the recovery of precious metals (PMs) from solution phases. The biosorptive recovery of PMs from waste solutions and secondary resources is recently getting paid attractive attention because their price is increasing or fluctuating, their available deposit is limited and maldistributed, and high-tech industries need more consumption of PMs. The biosorbents for recovery of PMs require specifications which differ from those for the treatment of wastewaters containing heavy metals and dyes. In this review, the previous works on biosorbents and biosorption for recovery of PMs were summarized. Especially, we discuss and suggest the required specifications of biosorbents for recovery of PMs and strategies to give the required properties to the biosorbents. We believe this review will provide useful information to scientists and engineers and hope to give insights into this research frontier.
生物吸附不仅是一种很有前途的去除重金属和染料的技术，而且还可以从溶液相中回收贵金属（PMs）。最近，从废溶液和二次资源中生物吸附回收 PMs 引起了人们的关注，因为它们的价格在上涨或波动，可用的储量有限且分布不均，而且高科技产业需要更多的 PMs 消耗。用于回收 PMs 的生物吸附剂需要的规格与处理含有重金属和染料的废水的规格不同。在这篇综述中，总结了之前关于生物吸附剂和用于回收 PMs 的生物吸附的工作。特别是，我们讨论并提出了回收 PMs 的生物吸附剂所需的规格以及赋予生物吸附剂所需性能的策略。我们相信，这篇综述将为科学家和工程师提供有用的信息，并希望为这一研究前沿提供一些见解。
