Functional Group Spatial Arrangement in Cationic Polymeric Nanotraps for Selective Perrhenate Anion Capture.
The selective capture of specific anions from complex wastewater remains a critical challenge in resource recovery. Although cationic polymers can adsorb anions through ion exchange, the influence of the spatial arrangement of the functional group on their selectivity is not well understood. In this study, two imidazol...
