METHOD FOR VOLTAMMETRIC DETERMINING ANILINE IN WATER AND WATER BODIES Russian patent published in 2017 - IPC G01N27/48 

FIELD: chemistry.

SUBSTANCE: method for voltammetric determining aniline in water and water bodies using a three-electrode system includes preliminary electrochemical modification of the glassy carbon indicator electrode of the system, electrochemical precipitation of aniline on the modified surface of the indicator electrode from the analyzed water, subsequent electrolysis of aniline upon changing the potential of the indicator electrode, recording an analytic signal on the volt-ampere curve, the identification of the aniline peak on the volt-ampere curve, and the determination of the aniline concentration from the peak value of aniline. The preliminary modifying electrochemical treatment of the indicator electrode is carried out in an aqueous solution of 0.1 M sodium sulfate with the addition of butanol in the ratio of volume parts of 19: 1, respectively.

EFFECT: express method that allows to determine aniline in water and water bodies at and below the MPC with the ability to record and unambiguously measure the analytical signal of aniline.
