Abstract
D. c. polarographic behavior of copper(II) in ethylenediamine-N,N,N′,N′-tetrapropionate (EDTP) and diethylenetriaminepentaacetate (DTPA) solutions was studied systematically. In EDTP solution, copper(II) ion invariably gave a single well-defined wave corresponding to the following reduction. CuX2−+nH++Hg+2e−=Cu(Hg)+HnXn−4 In the DTPA solution, copper(II) ion gave a single wave reversible in nature at pH below 5.0, corresponding to the following electrode reaction. (Remark: Graphics omitted.) At higher pH, however, two waves could be observed. The second step was irreversible and its wave-height increased with increasing pH at the expense of the height of the first step.This publication has 6 references indexed in Scilit:
