Polyacrylamide (PAA)-kaolinite (K) composite adsorbent was synthesized using K and PAA hydrogel, in-situ polymerization method as synthesis method. Adsorbent performance of the PAA-K composite for UO22+ ions was optimized: 400 mg L−1 at pH 4.5 at 25 °C. Synthesized PAA-K composite was featured by FT-IR, SEM–EDX, and XRD techniques. The maximum UO22+ ions adsorption capacity of the PAA-K composite was found to be 0.0656 mol kg−1. Thermodynamic parameters demonstrated that the behaviour of the adsorption was an endothermic and spontaneous. Finally, adsorption process suggested that the PAA-K composite had a significant adsorption capacity for the UO22+ ions.
