- 中文摘要:
The stability constants of the complexes between the trivalent lanthanide series of cations and series of azo-β-diketone ligands are reported. The measurements were conducted at 30° at an ionic strength of zero, in 100% methanol.
The relation between the overall stability constant (logρ2) and atomic number of the lanthanide elements, shows a buffer zone at the gadolinium area. The relation between (logβ2) and the basicity of the studied ligands (ΣpK’s) are also, discussed.
The overall stability values obtained reflected a great affinity of the organic ligamds for chelation with lanthanide ions. - 英文摘要: --
