Abstract
 The stability constant for the complex of UO22+ with a macrocyclic aminoether ligand, 1,7,10,16-tetraoxa-4,13-diazacyclooctadecane, has determined in aqueous solution. The conductivity and pH metric measurements suggest that the ligand forms a stable 1:1 complex with UO22+ ion, and the complex is an ionic form, UO2L2+, in aqueous solution. The fact that the ligand does not form a complex with lanthanides, such as Ce3+, Sm3+, and Nd3+ ions, in aqueous solution suggests a possibility of separation of the lanthanide elements from uranium matrix using the macrocyclic aminoet
