Abstract
Acomparative study of the reaction of La(III), Sm(III), Eu(III) and Gd(III) with some aryl Schiff bases has been carried out using polarographic and spectrophotometric methods. The optimum conditions for the determination of 1.39 – 20.84, 1.50 – 22.56, 1.52 – 22.80and 1.57 – 23.59 µg/ml of La(III), Sm(III), Eu(III) and Gd(III), respectively has been studied. The proposed methods show an average recovery of 98.20 % with SD not exceeing ± 0.058 indicating their reproducibility and sensitivity.
