  • Abstract The composite of synthetically produced hydroxyapatite (HAP) and polyacrylamide was prepared (PAAm–HAP) and characterized by BET, FT-IR, TGA, XRD, SEM and PZC analysis. The adsorptive features of HAP and PAAm–HAP were compared for UO 2 2+ and Th 4+ . The entrapment of HAP into PAAm–HAP did not change the structure of HAP. Both structures had high affinity to the studied ions. The adsorption capacity of PAAm–HAP was than that of HAP. The adsorption dependence on pH and ionic intensity… CONTINUE READING
