TEM Online Orthophosphate Analyzer
Under acidic conditions, orthophosphate reacts with ammonium molybdate and potassium antimony tartrate to form a phosphomolybdate complex, which is subsequently reduced by a reducing agent to produce a blue-colored complex, commonly known as molybdenum blue. The analyzer converts the color change before and after the reagent reaction into an electrical signal, from which the phosphate concentration in the water sample is calculated.
Product Application
● Influent tank, secondary settling tank, and high-efficiency settling tank of wastewater treatment plants.
