Özet

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 (Q(m)) 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.
