Orthophosphate Measurement
Method
The Molybdate-Vanadate method (also known as the Yellow method) detects orthophosphate (dissolved PO43-). A color reagent containing molybdate and vanadate is added to the sample. In an acidic environment, the PO43- ions are incorporated into the resulting polyanions. Depending on the concentration of PO43- ions, a yellow color develops, the intensity of which is proportional to the PO43- amount. The colored sample is then analyzed in a photometer at approximately 420 nm.
Application Areas for Orthophosphate Determination
Control of Coagulant Dosing
- Automatic cleaning reduces maintenance effort and increases operational reliability.
- Reduces coagulant costs through reliable and fast measurements, preventing overdosing.
- One device can handle up to two sample streams.
Monitoring of Wastewater Treatment Plant Effluent
- Precise results through automatic 1- and 2-point calibration.
- Simplified daily work through self-diagnostics with reagent level display.
- Declining effluent limits are easily met due to the low measurement range.
