- Scope
- This standard specifies the continuous flow-ammonium molybdate spectrophotometric method for the determination of phosphate and total phosphorus in water. This standard is applicable to the determination of phosphate and total phosphorus in surface water, groundwater, domestic sewage and industrial wastewater. When the detection light path is 50mm, the detection limit of this method for determining phosphate (calculated as P) is 0.01 mg/L, and the detection range is 0.04~1.00 mg/L; the detection limit for determining total phosphorus (calculated as P) The value is 0.01 mg/L, and the measurement range is 0.04~5.00 mg/L.
