✦ Synopsis

Ammonia is formed during potentiostatic reduction of sodium nitrite solutions on the nafioncomplex-coated electrode. When (NH,,)JMoO,(O,CC(S)(C,H~)~)J is present in NaNO, solutions a polarographic wave is associated to electrocatalytic reduction of nitrite ion. The wave height varies linearly on the concentration of nitrite ion, allowing a procedure for analysing this ion. This electrochemical hehaviour distinguishes the nitrite from the nitrate ions. The Mo(VI), MO(V), and Mo(IV) are involved in catalytic redox processes determining formation of NH: from nitrite ions.
