The present work is undertaken to make a systematic solution study of the complex formation of lanthanide (III) ions with the Schiff bases synthesized from salicylhydrazide with 1) 4- methoxy benzaldehyde 2) 3,4,5 trimethoxy benzaldehyde.
The interaction between Schiff bases and lanthanide ions like La (III), Ce(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III), Dy(III) and Ho(III) has shown 1:1 and 1:2 complex formation and the trend in logk values shown a break at gadolinium. The complex formation has been determined at 30°±0.1°C potentiometrically in 40% (v/v) Tetrahydrofuran water mixture and 0.1M (NaClO4) ionic strength.
