A METHOD FOR POLAROGRAPHIC DETERMINATION OF PHENYHYDRAZINE, which consists in recording a current on a mercury dripping electrode, characterized in that, in order to increase the selectivity of the determination, the sample to be analyzed is dissolved in ethyl alcohol or dimethylformamide, then the buffer solution is added in order to maintain the sample. ± 0, 5 and concentrations of ethyl alcohol or dimethylformamide in the range of 24-50 vol.% And polarograph in the anode potential range from -0.5 to +0.1 V. |
