A new, effective, and economic adsorbent (PAA-Do), consist of Polyacrylamide and Dolomite was synthesized chemically and used for removal of uranyl ions from aquatic medium. Characterization of new material was carried out by FTIR, SEM–EDX and XRD techniques. The maximum adsorption capacities (Qm) for PAA-Do was found by the Langmuir equation to be 0.477 mol kg−1. Adsorption kinetic was well-described by the pseudo first order kinetic. Recovery of adsorbent can be carried out by 1.0 mol L−1 HCl. The results of this study indicate that PAA-Do composites are good adsorbent candidates for uranyl removal.
