Background
Water is a source of life, and the quality of water directly influences the health and the aspects of life of all people. It can be said that the water quality directly affects the living standard of all water users.
Phosphorus in water may be present as elemental phosphorus, orthophosphates, condensed phosphates, pyrophosphates, metaphosphates, organic group-bound phosphates, and the like. The main sources of the detergent are domestic sewage, chemical fertilizers, organophosphorus pesticides, phosphate builders used in modern detergents and the like. Phosphates can interfere with the coagulation process in waterworks. Phosphorus in the water body is a key element required by the growth of algae, and excessive phosphorus is a main reason for causing the pollution and the foreign odor of the water body, causing the eutrophication of lakes and the red tide of gulf.
In the prior art, automatic instruments for detecting total phosphorus are available, but the total phosphorus reagents used by the instruments are mostly imported originally, and the reagents are not stable enough, are easy to deteriorate, cause inaccurate detection records, and are high in price.
