In the TS 7159 standard published by the Turkish Standards Institute (TSE), a manual spectrophotometric method for the determination of ammonium in water is defined. While preparing this standard, the following standard published by the International Standards Organization (ISO) was taken into consideration: ISO 7150-1 Water quality - Ammonium determination - Part 1: Manual spectrometric method.
This test method applies to most raw and waste water, including drinking water. However, highly colored or salty water must be distilled prior to analysis. With this method, ammonium nitrogen concentration up to 40 mg/l can be determined using a maximum of 1 ml of sample. However, it is possible to determine much higher concentrations by taking fewer samples.
Water is important in the life of all living things and the quality of water is therefore a decisive factor for human health and nature. Therefore, it is of great importance to carry out microbiological, chemical and physical tests in drinking or utility water.
The ammonium ion is a cation found in water. Ammonia is a substance normally found in gaseous form, used as a refrigerant gas in large refrigeration plants, and is also used in industry in cleaning chemicals. In addition, ammonium is useful in agricultural activities, it is given to plants as artificial fertilizer. This fertilizer meets the nitrogen and sulfur needs of plants.
However, ammonium in drinking and utility water is harmful. For today, the highest 0,5 mg/l limit has been determined for the amount of ammonium in water. The presence of ammonium in the water means that it is mixed with domestic waste, industrial waste and manure. Nitrogen is a parameter used by bacteria as a source of nutrients and is frequently seen in waters.
The spectrophotometric method is a quantification method based on the ability of the colored substance placed between the light source and the prism to absorb some colors of the light spectrum and show weak or strong bands in the spectrum according to concentration.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides ammonium determination services in water by manual spectrophotometric method, within the scope of TS 7159 standard, with its trained and expert staff and advanced technological equipment.
