METHOD OF DETERMINING NITRIC ACID NITROGEN OXIDES BY VOLTAMMETRY TECHNIQUE ON SOLID ELECTRODES

摘要

Field of the. The invention relates to methods for determining the nitric acid and nitrogen oxides and can be used in processes for the preparation of nitro compounds by nitration with nitric acid and its mixtures. SUMMARY OF THE INVENTION: determination is carried out in an 88-100% sulfuric acid at a temperature of 10-80 & amp; deg; C. Magnetic potential sweep rate is 0.001-0.5 V / s. The platinum may be used as a working electrode, gold, silicon, glassy carbon, etc. Table 2.
