Differential Pulse Voltammetric Study of Complexes of Rare Earth Ion(Eu3+) with Glutarate and 1,2-Diminopropane |

Abstract: | Abstract The mixed complexes of Eu (III) with glutarate (Gluta) and 1,2-diaminopropane (DMPA) have been studied at 25°C, μ=0.12(NaClO4) by differential pulse voltammetry(DPV). The reduction process in each case appears to be quasi-reversible and diffusion-controlled. The stability constants have been measured by Schaap and McMasters′ method. The stability constants of three mixed complexes formed are logβ11=7. 414 for [Eu(Gluta) (DMPA)]+, logβ21 = 8. 506 for [Eu(Gluta)2 (DMPA)]? and logβ12 = 9. 984 for [Eu(Gluta) (DMPA)2]+. |
