0-(N-α, thiophenylideneimino) benzene sulphonic acid (HTB) and 2-(N-α, thiophenylideneimino) ethane sulphonic acid (HTE) and their lanthanon chelates were synthesized and studied. Irving-Rossotti method was followed to determine the dissociation constant of the ligands and formation constants of its chelates with La (III), Ce (III), Pr (III), Nd (III), Sm (III), Gd (III), Tb (III), Dy (III) and Ho (III) metals in aqueous medium (μ= 0.01 M, 0.05 ...
