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.en10.1007/s10967-023-08820-9info:eu-repo/semantics/restrictedAccessPolyacrylamide, Pollen, Composite, Uranyl, Adsorption, IsothermArticle332224822392-s2.0-85147924665Q2WOS:000931743800002Q2
