CATALYTIC POLAROGRAPHIC REDUCTION OF NITRATE ION IN THE PRESENCE OF IRON(II) AND IODATE AT DROPPING MERCURY ELECTRODE

Abstract Polarographic reduction of nitrate took place in the ascending branch of an Fe(II) reduction wave in an unbuffered solution (pH 4–6) of a supporting electrolyte that contained iodate. In the potential region of reducing nitrate, the current varied periodically of which the period depended on the experimental condition.
