| Abstract |
The purpose of this study was to determine the amount of ammonia produced during electrolysis of silver nitrate solutions using metal and inert electrodes during the electrolytic recovery of silver. Trials using different experimental conditions and electrode systems confirmed that the nitrate was reduced to ammonia. The ammonia concentration in the solution showed that the yield of conversion of nitrate to ammonia was higher than 40%. It was found that ammonia is formed under both acid and alkaline conditions with a high yield, and that the pH fluctuates and changes very rapidly from acid to alkaline conditions at critical points in the electrolysis. |
