Abstract
METHOD OF APPLYING UREA TO SOLUTIONS CONTAINING NITROUS ACID TO REDUCE THE EMISSION OF NITROGEN OXIDE, AND INSTALLATION OF THE CORRESPONDING MEASURE. ABOVE A SOLUTION (FORMED BY REACTIONING PHOSPHATE OR OTHER MATERIALS WITH NO3H OR ABSORBING NITROGEN OXIDES IN ACID SOLUTIONS) ADD, IN A CONTROLLED WAY, MEASURING THE CONCENTRATION OF NO2H IN THE SOLUTION, FOR WHICH IT IS USED CONTINUOUS VOLTAGE SOURCE (24) UP TO 1.5 V, WITH A TERMINAL CONNECTED TO THE WALL OF THE SOLUTION CONTAINER (25) AND WITH ANOTHER CONNECTED TO A MEASURING ELECTRODE, LOCATED IN THE SOLUTION. IT ALSO INCLUDES A RESISTANCE (23), IN SERIES WITH THE MEASURING ELECTRODE AND THE VOLTAGE SOURCE, THROUGH WHICH A POTENTIOMETRIC RECORDER (26) IS CONNECTED THAT MEASURES THE DROP IN IT.
