Detection principle of the total phosphorus detector in the water quality test

Total phosphorus is one of the most common parameters in water quality detection, which is the sum of organophosphorus and inorganic phosphorus in the water body, and it is also one of the important indicators to assess water quality.Total phosphorus tester is a common instrument in water quality detection, which can quickly and accurately detect the total phosphorus content in the water.So, what is the detection principle of the total phosphorus detector in the water quality detection?The detection principle of the total phosphorus detector is based on the spectrophotometric design. The instrument emits a section of light, the measured substance absorbs light at a specific wavelength or within a certain range, and the concentration of the measured substance is determined by measuring the absorbance of light.The detection process of the total phosphorus tester mainly includes sample preparation, sample processing and photometry. These steps are all designed to ensure the accuracy and reproducibility of the assays.

Phosphorus in domestic sewage is mainly a large number of detergents containing phosphorus, chemical, paper making, rubber, dye, textile printing and dyeing, pesticide, petrochemical, medical medicine, food processing and other industrial wastewater also contains a large number of phosphorus containing compounds.The use of chemical fertilizers and pesticides will also cause the increase of phosphorus content in surface water.When the phosphorus content in the water is too large, it will cause water eutrophication, cause algae outbreak and aquatic life death and other problems, and have an irreversible impact on the water environment.
