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-L1)
and 2-hydroxy-3-bromo-5-chloro-1-(a-phenylimino) ethyl benzene (Ligand-L1)
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.
