[Display omitted] Rhenium (Re) has a critical role in the field of aerospace and defense. However, due to its scarcity, it is typically found associate with other metals such as Mo, Cu, Pb in natural ores. To extract Re and enrich its concentration, extraction from solutions has proven to be the most effective method. Therefore, developing efficient Re recovery technology is significant for its adequate application and the national safety. Adsorption, as a green and efficient technique, shows great potential for Re recovery from low or ultra-low concentration solutions. In recent years, numerous adsorption schemes have been developed to separate and enrich Re from liquid phase. In this review, in order to summarize the process of Re adsorption, the recent research about developments of Re adsorption materials and the critical factors controlling the Re adsorption process were provided. The interaction between adsorption performance and surface area, pore specificity, functional groups and charge properties were discussed. Additionally, the influencing factors of the adsorption process and mechanism were reviewed. Finally, the challenges and possible directions in this field of Re adsorption from solution were discussed and highlighted. [ABSTRACT FROM AUTHOR]
