Complexing ability of ligands bearing hydroxyaminocarbonyl group and amino group with UO<SUB>2</SUB><SUP>2+</SUP> in an aqueous solution were examined by the potentiometric method using MINIQUAD program. Stability constants of 2-aminoacetohydroxamic acid complex with UO<SUB>2</SUB><SUP>2+</SUP> are logβ<SUB>1</SUB>=10.45, logβ<SUB>2</SUB>=18.95. They are far larger than those of acetohydroxamic acid complexes. The β<SUB>1</SUB> and β<SUB>2</SUB> are almost the same as β<SUB>1</SUB> and β<SUB>2</SUB> of the acetamide oxime (acetoamidoxime) complexes.
