Abstract
The interactions of La (III), Nd (III) and Pr (III)
with 2-hydroxy-5-chloro-1-(a-phenylimino) ethyl benzene (Ligand-L₁),
2-hydroxy-5-chloro-1-(a-para methylphenylimino) ethyl benzene (Ligand-L₂) and
2-hydroxy-3-bromo-5-chloro-1-(a-phenylimino) ethyl benzene (Ligand-L3) have
been investigated by pH-metric technique at 0.1 M ionic strength at 26 ± 0.1°C
in 70% DMF-water mixture. The data obtained were used to estimate the values of
proton-ligand stability constants (pK) and metal-ligand stability constants
(log K). It is observed that La (III), Nd (III) and Pr (III) metal ions formed
1:1 and 1:2 complex with all the three ligands.
