Polarographic studies of iron complexes as potential ...

1987-1-1 · A differential pulse polarogram recorded for a 0.1 mM 1:1 mixture of iron(III) and TTHA at pH 7.2 exhibited one peak at ca 0.0 V, and a double peak with Ep values at ca. --0.20 V and -0.28 V. The heights of the peaks were found to depend on the time between the preparation of the complex and the recording of the polarogram.
