摘要：

3-[4-Sulfophenylazo]pentadione-2,4,3-[5-sulfonaphthylazo]pentadione-2,4, 3-[2-hydroxy-3-sulfo-5-chlorophenylazo]pentadione-2,4 and 3-[2-hydroxy-3-sulfo-5-nitrophenylazo]pentadione-2,4 were synthesized from acetylacetone. The stability of their complexes with some metals was studied by potentiometric titration. It was shown that the stability of the complexes chancres in the sequence Fe > Cu > UO2 > Ni > Co > Zn > Cd > Mn > Mg > Ca.
