Promising framework of nanocomposite materials: synthesis and radio-lanthanides labeling for nuclear medicine application

Incorporation of fulvic acid (FA) into the framework of hydroxyapatite particle to synthesis NHAP functionalized with FA (NHAP-FA) as a new smart nanocomposite is achieved. Some analytical methods such as EDX, FTIR, XRD, and TEM defined it. Preliminary study on the possible radiolabeling of NHAP-FA with 141,143Ce, 152,154Eu, 159,161Gd as represented radio-lanthanides that are gaining more attention in the last decades is carried out. The obtained results were revealed that a significant sorption affinity of radio-lanthanides (~ 98%). Application on the environmental remediation towards the removal of some radionuclides (152,154Eu, 60Co, 99Mo, 63Ni and 137Cs) has been evaluated.
