Abstract
One of the problems of nuclear energy is the technology of disposal of liquid radioactive waste. One strategy for handling them is to fractionate them to isolate long-lived and radiotoxic nuclides, and then separate them into separate fractions based on their half-life and chemical behavior. The most difficult process in fractionation technology is the extraction separation of trivalent actinides and lanthanides, since their properties are very similar. To study the extraction separation of actinides and lanthanides, it is necessary to know the stability constants of complexes. In this work, the complex formation reactions of uranyl nitrate with substituted 2,2'-bipyridine-6,6'-dicarboxamide were studied by spectrophotometric titration and the stability constants of the complexes were calculated.
