The effect of gelatin on the polarographic waves of <I>p</I>- and <I>o</I>-nitroanilines has been investigated,<BR>(1) Maxima of the polarographic waves of these compounds which occur in the supporting electrolyte without gelatin were supressed by adding 0.005-0.01% of gelatin to the supporting electrolyte.<BR>(2) The wave of each of these compounds splitted into two waves when the supporting electrolyte contained more than 0.01% of gelatin.<BR>(3) The ratio of the wave heights of the second wave to the first increased with increasing concentration of gelatin, and it was different between <I>p</I>- and <I>o</I>-compounds in the supporting electrolyte containing the same concentration of gelatin.<BR>(4) The wave heights of the first and the second waves of each compound were proportional to the concentration.<BR>(5) These double waves were applied to the simultaneous determination of both compounds, with the result that the procedure was available for rough estimation of content.
