Silica gel nanoparticles (SGNPs) have been successfully prepared and utilized for capturing aqueous uranyl ions (VI) by batch sorption. The IR, SEM, PXRD, TGA, and DSC characterize and study the nanoparticles. The maximum efficiency of SGNPs toward capturing UO22+ ions is found at pHi = 7, Ci = 1.0 mg L-1, T = 25 C-degrees, 80 rpm, and dosage = 2 g L-1 achieving 99% within 40 min of equilibrium sorption's. U(VI) ion sorption follows the Freundlich isotherm model (R-2 > 0.999) and the pseudo-second-order kinetic model (R-2 > 0.999). Based on these promising results, we candidate silica gel nanoparticles (SGNPs) as an effective filter for capturing low concentrations of uranium (VI) ions from the water.
