Detection Principle
UPotassium persulfate solution is added to the water sample for heating and dissolving for a period of time, the phosphorus in the water sample is converted into orthophosphate. After cooling, reducing agent and chromogenic agent are added, orthophosphate is reduced by ascorbic acid after reaction with ammonium molybdate and potassium antimony tartrate to generate a blue complex. The absorbance is detected at a specific wavelength, according to Lambert Beer's law, there is a linear correlation between the total phosphorus content in the water and the absorbance. Last the total phosphorus concentration in the water is detected.

Characteristics
1. The analyzer is miniaturization in size, which is convenient for daily maintenance;
2. High-precision photoelectric metering and detection technology are used to adapt to various complex water bodies;
3.Three ranges (0-2mg/L), (0-10mg/L) and (0-20mg/L) satisfy most of the water quality monitoring requirements. The range can also be extended according to the actual situation;
4. Fixed-point, periodic, maintenance and other measurement modes satisfy the requirements of measurement frequency;
5.Reduces the operation and maintenance costs by low consumption of reagents;
6.4-20mA,RS232/RS485andothercommunicationmethodssatisfy thecommunication requirements;
Applications
This analyzer is mainly used for real-time monitoring of total phosphorus (TP)
concentration in surface water, domestic sewage and industrial wastewater.
