Reduction potentials of 2, 4-dinitro-6- and 2, 4-dinitro-4-cyclohexylphenol was measured at pH 1-10. It was thereby found that the separatory determination of 2, 4-dinitro-6-cyclohexylphenol in a mixture is possible by the polarographic method if carried out in a buffer solution of around pH 7. The errors in the determination were influenced naturally by the temperature, pH, and the concentration of alcohol, but an unexpected source of great error was found to appear if extreme care is not taken in the measurement of wave height. Absolute errorr of ±2% should be taken into consideration for samples containing around 85% of 2, 4-dinitro-6-cyclohexylphenol.
