Polyacrylamide-pollen (P@PAA) composite adsorbent was synthesized using polyacrylamide hydrogel and pollen via in situ polymerization method. The adsorptive properties of P@PAA hybrid polymer composite adsorbent for the removal of UO22+ ions were investigated. Structural characterizations showed various functional group variations in the P@PAA composite adsorbent. The maximum adsorption capacity of UO22+ ions was found to be 0.695 mol kg(-1). Thermodynamic parameters confirmed the spontaneous adsorption of UO22+ ions onto P@PAA hybrid polymer composite.
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 findings 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 clarified that the adsorption was spontaneous.
