PAMPS PolyHIPEs: The Role of Shape, Porosity, and Sulfonate Group Density on Metal‐Ion Adsorption From Water

open access: yesJournal of Applied Polymer Science, EarlyView.
This study demonstrates how pore architecture, shape, and sulfonate group density influence the adsorption of Zn2+, Fe3+, and Al3+ by PAMPS polyHIPEs. Beads and monoliths exhibit distinct transport behavior compared to commercial 77H resin. The results offer design guidelines for optimizing ion‐exchange polymers to improve performance in water ...
