Ammonia, made of nitrogen and hydrogen, is important for checking water quality. It's key to health in nature and life underwater. Found in water, ammonia often comes from farms and factories. It can make the water too rich and cause harm to fish-like creatures living there. This changes finding ammonia, which is not only a science task but something needed to protect the environment. Nowadays, sensors are very important for this job. They help us to watch levels of ammonia in different water places quickly and correctly all the time.

Ammonia Detection

Ammonia is harmful to aquatic life and unfit for human consumption due to its negative impact on water quality. Because ammonia promotes nitrification, which lowers oxygen levels, aquatic habitats suffer. As a result, protecting the environment and meeting water quality criteria established by international environmental authorities depend on accurate ammonia level detection and monitoring.

Types of Ammonia Sensors for Detection

Electrochemical Sensors

Because of their sensitivity and selectivity, these ammonia sensor find extensive utility. A current proportionate to the ammonia concentration is generated by their operation, which is based on the oxidation or reduction of ammonia on an electrode surface. Due to their accuracy and inexpensive cost, electrochemical sensors have gained a reputation for excellence.

Optical Sensors

Optic sensors can detect ammonia by detecting changes in light intensity or wavelength when exposed to the gas based on the principles of light absorption and fluorescence. These sensors are very precise and resistant to water-borne interference.

Colorimetric Sensors

For these, the presence of ammonia causes a reagent to change color. A good indicator of the ammonia content is the degree to which the color changes. Their intuitive design and ease of usage make them ideal for use in the field.

Working Principles of Ammonia Sensors

Direct contact between an ammonia and a sensitive electrode is used in electrochemical sensing. An electrical signal that may be used to measure the concentration of ammonia is generated by the electrochemical process.

Uses ammonia-sensitive light-sensitive materials. The material's optical characteristics, such as absorbance or fluorescence, are changed due to this reaction, and the quantities of ammonia may be determined by measuring these changes.

Chemical processes that cause a change in color when ammonia is present are the basis of colorimetric detection. Ammonia content is determined by quantitative analysis of this colorimetric shift.
