Introduction
Ammonia is a toxic gas, a colorless, strong-smelling, can irritate the skin, eyes and lungs [1].
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. Excess ammonia in the water can lead to living things in the
water is contaminated and cause death. Who had high levels of ammonia can be found at the bottom of
the lake with the condition without oxygen, or anoxic[4]
Extreme toxicity of ammonia and abuse of toxic ammonia as a result the amount of research in the
methods of development for the detection of ammonia. Previously to analyze ammonia used various
methods is titrimetric, voltammetry, potentiometric, electrochemical method, and ion chromatography.
However, this method takes a long time in the process involves the use of sophisticated instruments
with a high detection limit and require special expertise. Ammonia analysis method based on the color
change is monitored and has been studied for the past few years due to the implementation of simple,
cheap and fast [5]. Spectrophotometric method to determine ammonia through the formation of color
by using the metal as a complexing based on the absorption of UV-Vis.
