Description
Standard colorimetric method for measuring soluble reactive phosphorus and total dissolved phosphorus in water samples using spectrophotometry. Total dissolved phosphorus samples are first digested with K2S2O8 in a pressure cooker.
Typical Equipment
- pressure cooker
- K2S2O8
- Thermo Scientific GENESYS 10S UV-VIS Spectrophotometer
Output Measurements
- soluble reactive phosphorus concentration
- total dissolved phosphorus concentration
