Use of a Hydrogen Anode for Nitrate Waste Destruction

Abstract

The use of a hydrogen gas-fed anode and an acid anolyte in an electrochemical cell used to destroy nitrate is demonstrated. A mixed Na 2SO 4/H 2SO 4 anolyte is shown to favor nitrate cell performance and the generation of a higher hydroxide ion concentration in the catholyte. The suggested scheme is an apparent method of sodium sulfate disposal and a possible means through which ammonia (to ammonium sulfate, fertilizer) and hydrogen gas could be recycled through the anode side of the reactor. This could result in a substantial savings in the operation of a nitrate destruction cell.
