Abstract :

 The interaction of Ce (III), Tb (III), Nd (III), Gd (III), &Dy (III), metal ions with Idoquinol 5,7–di–iodo–8–quinolinol

(ligand – 1) And Chlorothalidon 2–chloro–5–(1–hydroxy–3–oxo–1,2–dihydroisoindol–1–yl)–benzenesulfonamide (ligand –
2) have been investigated by pH – metric technique at 0.1 M ionic strength at 27 ± 0.10c in 70% dioxane – water mixture. The data obtained were
used to estimate the values of proton–ligand stability constant (pK) and metal– ligand stability constant log K. It is observed that Ce (III), Tb (III),
Nd (III), Gd (III), & Dy (III), metal ions formed 1:1 and 1:2 complexes with all the ligands.
