Electrochemical oxidation of ammonia in alkaline solutions: its application to an amperometric sensor

Elucidation of the Electrochemical Oxidation Pathway of Ammonia in Dimethylformamide and the Room Temperature Ionic Liquid, 1‐Ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide

“…Advances have been made in the development of amperometric sensors [10] and selected catalytic oxidation of ammonia to nitrogen has recently been explored as a possible method to reduce ammonia waste [12]. However, to our knowledge, very few studies have been reported in nonaqueous systems [13] and the analytical significance of the oxidation of ammonia has never been examined.…”

Determination of Ammonia Based on the Electrochemical Oxidation of N,N′-Diphenyl-1,4-phenylenediamine in Propylene Carbonate

“…4,5 Chemical sensors provide vital sensing platforms for monitoring in a large plethora of technologies and applications, which include safety, pollution, medical engineering and industrial processes. 6 Sensors need to be fast, specific, reliable, sensitive, low cost and have the possibility for miniaturisation. 2,6,7 For such sensor designs, electrochemical strategies are advantageous due to their rapid response and their inherent low cost but high sensitivity.…”

“…6 Sensors need to be fast, specific, reliable, sensitive, low cost and have the possibility for miniaturisation. 2,6,7 For such sensor designs, electrochemical strategies are advantageous due to their rapid response and their inherent low cost but high sensitivity. [8][9][10][11] Generally in the above sensor designs, including those for ammonia, the electrolyte employed is water based.…”

Anthraquinone functionalized carbon composite electrode: Application to ammonia sensing

“…Due to its toxicity, the determination of ammonia is more essential in a number of applications including industrial hygiene, environmental protection, clinical diagnosis and the monitoring of leakage from refrigeration systems etc. [1][2][3]. Ammonia may be released to the atmosphere by volatilization from the following sources: decaying organic matter, livestock excreta, fertilizers applied to soils, venting of gas, leaks or spills during commercial synthesis, production, transportation, or refrigeration equipment failure, sewage or waste water effluent; burning of coal, wood and other natural products and volcanic eruptions.…”
