Synthesis and characterization of a new hybrid polymer composite (pollene@ polyacrylamide) and its applicability in uranyl ions adsorption

In this study, polyacrylamide-pollen (P@PAA) composite adsorbent was synthesized by in situ polymerization method using polyacrylamide hydrogel and pollen. The adsorptive properties of the P@PAA hybrid polymer composite adsorbent were investigated for the removal of UO22+ ions. The fndings obtained as a result of the structural characterizations showed that the P@PAA composite adsorbent has various functional group variations. The max adsorption capacity of UO22+ ions was 0.695 mol kg−1. The thermodynamic parameters of the adsorption of UO22+ ions onto P@PAA hybrid polymer composite were determined and it was clarifed that the adsorption was spontaneous.
