Ammonium Sensor: Monitoring Water Sample And Knowing Its Benefits

One of the traditional analytical techniques used to identify ammonium levels is through the ammonium sensor, which has piqued the collective research interest due to its benefits, including cost-effectiveness, user-friendliness, and downsizing capability, which allows for convenient portable tests.

Furthermore, the ammonium sensor is a half-cell sensor that can identify ammonium contents in a liquid sample. This sensor is a solid-state and was developed based on carbon nanotube innovation. Consequently, the ammonium sensor has a membrane-selected region and a strong body capacity. An ammonium sensor may be used with mV or Ion metre and a reference electrode. Most of all, it is appropriate for detecting NH4+ contents in sectors such as water supply, filtered water, sewage, and overall quality of water.

What Is Ammonium?

Ammonium is a nitrogen-containing chemical that aquatic plants may ingest and combine into amino acids, proteins, and other compounds. Ammonium levels over a certain threshold may promote the production of algae and seawater plants. Bacteria may also structure ammonium to nitrate, lowering dissolved oxygen during the nitrification procedure.

Moreover, ammonium may be observed in several salts, including nitrate, carbonate, and chloride. The majority of simple ammonium salts are highly water-soluble, except for ammonium hexachloroplatinate since its production was initially employed as testing for ammonium. Ammonium compounds of nitrate and, in particular, perchlorate are very hazardous, and in these circumstances, ammonium serves as a reduction agent.

Application Of Ammonium Sensor

The ammonium sensor is the ideal innovation for precisely measuring in water samples. It aids in improving productivity and lowering the energy expenditures of your oxygenation procedures. The sensor does not need any chemicals, which saves you even more money. Moreover, an ammonium sensor can assist in providing reliable data in analysing your water sample because of its resilience, which mixes optimum procedure and data consistency with the most excellent operational satisfaction and streamlines condition monitoring.

The Importance Of An Ammonium Sensor

The ammonium sensor makes it simple to monitor the ammonium molecules (NH4+) content in water. Many have already used it to evaluate various water quality and assess the ammonium content in foods and other products. Ammonium is a positive electrode chemical formed when ammonia is diluted with water containing an extra hydrogen ion, thus the NH3 to NH4+ proportion is affected by the pH and water temperature. The greater the level of ammonium owing to a rise in H+ ions, the lesser the pH and the hotter the water.

Ammonium In Drinking Water

Ammonium levels in the water supply must be evaluated to ensure good health and well-being. It could be obtained during monochloramine decontamination or due to corrosion from materials used in pipework installation. Because chlorine reacts with ammonium, lower disinfecting effectiveness is anticipated if the water supply includes more than 0.2 mg/L of ammonium.

Ammonium In Wastewater

Ammonium concentrations in wastewater may exceed dangerous levels owing to microbial activity. Evaluating ammonium levels in wastewater treatment facilities is critical prior to effluent discharged to protect local marine life.

Where Is Ammonium Quantification Needed?

Ammonium is most often found in wastewater as a byproduct of the formation of urea. As a result, water sources with an ammonium content of 1 mg/l are insufficient. The use of ammonium sensors aids in knowing the condition of your water and avoiding significant complications.

The ammonium sensor may be used for a variety of purposes, including:

  • Investigating the transmission of dangerous compounds from scattered origins.
  • Assessing aquaculture vegetation for filthiness caused by high nutrient concentrations.
  • Monitoring nutrient composition in waterways.
  • Calculating the amount of ammonia supplied by fertilisers.
  • If samples are oxidised to transform NH3 to NH4+, the balance may be monitored, and water levels are usually shown.

The Benefits Of An Ammonium Sensor

The following are some benefits of using an ammonium sensor:

  • Ammonium and nitrate were detected immediately without the requirement for costly sample preparation.
  • The alternative assessment of chloride and potassium adjusts for crossing sensitivity and assures repeatable testing findings.
  • Because of the automated cleaning device, servicing is minimal.
  • There is no need for a measurement jar or specimen pumps since it is mounted immediately on the waterway.
  • Because sensor-specific information is stored, it is simple to handle.

Dissolved Oxygen Metre

Among the ammonium sensors is the dissolved oxygen metre, which utilises an optic sensor, galvanic, amperometric, polarographic, and electrochemical to detect the quantity of dissolved oxygen content in a water sample. It is an essential water condition measure that influences the chemical reactivity of sample water, water supply flavour, and aquatic life. Moreover, fish hatcheries, aquariums, sewage treatment, and wastewater rehabilitation are common uses.

Measuring Dissolved Oxygen Concentration

A dissolved oxygen metre sensor may be used to collect or continually evaluate the content of diluted oxygen in the water. Dissolved oxygen sensors are commonly classified into three types:

  • optical sensors
  • polarographic sensors
  • galvanic sensors

Moreover, each kind of dissolved oxygen metre operates on a somewhat different concept. As a result, based on the water control and monitoring, every dissolved oxygen metre type has benefits and drawbacks.


Assessing ammonium has piqued the interest of researchers from a variety of disciplines because it is a critical component in ecological and medicinal purposes. Ammonium, for instance, is thought to be a quality basis for groundwater sources as well as a possible biomarker of an enzyme byproduct in critical physiological processes. Moreover, an ionophore’s selectivity for ammonium over other ions is a characteristic that essentially determines the ammonium sensor limit of identification when doing tests in actual data.
