The polarographic behaviour of uranium and tellurium has been studied in the presence of increasing concentration of complex forming agent viz. ϵ‐caprolactam at p H 4.4 for U(VI) and at p H 10.0 for Te(IV) at μ=0.1 M KNO 3 . In both cases the waves have been found to be diffusion controlled and irreversible. The values of kinetic parameters (σπ a and K ° f,h ) have been calculated as a function of the ligand concentration. Method is suitable for the quantitative determination of these metals individually and simultaneously with the effect of diverse ions.
