Introduction
Ammonia is a toxic gas, a colorless, strong-smelling, can irritate the skin, eyes and lungs [1].Spectrophotometric method to determine ammonia through the formation of color
by using the metal as a complexing based on the absorption of UV-Vis.Ammonia can be explosive or flammable by volume of 15% to 28%[2] When the concentration of 
ammonia exceeds 300 ppm, it can cause severe injuries on the skin respiratory system, skin, eyes and 
damage human cells[3]
Waste from farms, factories, chemical industries, and mines are a common source of ammonia 
which can contaminate water systems.Previously to analyze ammonia used various 
methods is titrimetric, voltammetry, potentiometric, electrochemical method, and ion chromatography.
