The aim of this work is directed to prepare nanoparticles of egg shell hydroxyapatite-humic acid (ESHAP-HA) as a novel composite material. FTIR, EDX, TEM, XRD, and SEM identified it. Sorption characteristic studies on ESHAP-HA at different pH of solutions, shaking time, initial ion concentration and complexing agent were performed at  152,154 Eu,  99 Mo and  63 Ni. The results were demonstrated that selectivity removal of  152,154 Eu (~96 %) rather than  99 Mo (8.5 %) and  63 Ni (26.7 %). The sorption capacity of  152,154 Eu(III),  63 Ni(II) and  99 Mo(VI) are 80.1, 12.5 and 2.3 mg/g, respectively, onto the ESHAP-HA nanoparticles. Application on the eclectic removal of  152,154 Eu from mixed radionuclides ( 152,154 Eu,  60 Co, and  137 Cs) solution has been evaluated. It concluded that the prepared ESHAP-HA composite material is a promising and recommended for separation of radio lanthanides and/or actinides (such as Am) from nuclear liquid waste and/or contaminated aquatic environmental.
