Abstract

Metoda pentru reducerea emisiei de oxizi de azot din solutiile cu continut de acid azotos, conform inventiei, este utilizata în procesul de obtinere a îngrasamintelor minerale în asa numitul procedeu nitro-fosfat si consta în aplicarea unui curent continuu între electrozii de pltina din solutia de acid nitric, unde tensiunea este mai joasa decît potentialul de descompunere a apei, curentul electric între electrozi fiind aproximativ proportional cu concentratia de acid azotic, acest amperaj putîndu-se utiliza pentru o masurare liniara a concentratiei relative de acid azotos, în felul acesta amperajul masurat depinde în primul rînd de suprafata anodului si deci sistemul poate fi simplificat prin utilizarea electrodului de platina ca anod si a peretilor vasului ca si catod.
