Abstract

Abstract

In this paper,the effect of the molar ratios of ruthenium (Ru)-iridium (Ir) on the microstructure,chemical properties,electrochemical performance,and denitrification performance of high ammonia-chloride wastewater were investigated.The results illustrated that Ru-Ir solid solution was a rutile crystal with uniform grain distribution and tight connection.The electrochemical performances of the electrodes were tested by electrochemical techniques.And the electrochemical performance of the Ru-Ir electrode first increased and then decreased with the increase of the molar ratio of Ir.The electrochemical properties of Ru_2/3Ir_1/3O₂ electrodes were the best when the molar ratio of Ru-Ir was 2:1.The chlorine evolution potential,corrosion current density,and conductivity of Ru_2/3Ir_1/3O₂ electrode were 0.998,0.755,and 1.816 times those of RuO₂,respectively.In the removal process of ammonia-nitrogen in high chloride ammonia-nitrogen simulated wastewater,the electrode with the best removal effect of ammonia-nitrogen was Ru_2/3Ir_1/3O₂ electrode,and when the current was 0.5 A,the ammonia-nitrogen removal rate could reach 75.2% in 50 minutes.This paper proved that electrocatalytic technology could effectively treat high chloride ammonia-nitrogen wastewater.
