Standard Test Methods for Ammonia Nitrogen In Water 1Performance, MeasuringSpectrophotom, Near InfraredASTM D1426, 2012. Standard Test Methods for Ammonia Nitrogen in Water. American Society for Testing Materials, West Conshohocken, PA.
Based on this, a novel spectrophotometric method with flow injection analysis has been established to determine ammonia nitrogen in water. Experimental parameters related to the flow injection method and the reaction were optimized throughout the experiments based on univariate experimental design. The ...

The electrochemical nitrogen reduction reaction (ENRR) can allow the production of ammonia from nitrogen and water under ambient conditions and is regarded as a sustainable alternative to the industrial Haber–Bosch process. However, electrocatalytic systems that selectively and efficiently catalyse nitrog...
Ammonia (chemical formula: NH3) is a compound of nitrogen and hydrogen. As a colorless pungent gas, it is highly soluble in water to become the liquid ammonia. It is also one of the most abundant nitrogen-containing compound in the atmosphere. It provides the fundamental nutrients demands for...
ammonium ion in the water environment to determine the concentration of ammonia nitrogen. Use a pH electrode as a reference electrode for better stability. The concentration of ammonia nitrogen in the measurement process is easily interfered by potassium ions, so potassium ion com...
It is used to measure various parameters such as chemical oxygen demand (COD), ammonia nitrogen and total phosphorus in surface water, reclaimed water, urban sewage and industrial wastewater. Features •Imported high-quality integrated chips are used to ensure that the instrument can work ...
