- 論文の詳細を見る
The normal pulse polarogram of Fe(II) showed a double-wave behavior in an unbuffered solution containing iodate. The results of pulse polarographic and cyclic voltammetric studies indicate that colloidal Fe(OH)<SUB>2</SUB> formed by the reaction between aqua-Fe(II) and OH<SUP>−</SUP> arising from the iodate reduction is responsible for the second wave. A catalytic wave was observed in the presence of chlorate in Tast polarography. The catalytic wave which appears to be a polarographic maximum, has an abnormal form, in which the current increases at every second or third drop because of the depletion of colloidal Fe(OH)<SUB>2</SUB> around the electrode. The catalytic current is due to the reaction of chlorate with colloidal Fe(OH)<SUB>2</SUB> formed in the vicinity of the electrode.
