In this paper, the research progress of separation and enrichment of gold ions (Au3 + and Au +) in liquid phase based on organic functional materials such as chemisorption fibers (ion exchange and chelating fibers), activated carbon fibers and resins Including organic functional fibers and resins containing various functional groups such as N, O and S, experimental theoretical study on adsorption of gold ions in liquid phase by activated carbon fibers, pre-enrichment analysis and testing, and practical application in hydrometallurgy. For different adsorbent pairs Gold ion adsorption behavior, adsorption mechanism, influencing factors were discussed. The advantages of reactive materials and the existing problems are pointed out, and the prospect of their applications is forecasted.
