Overview
The rapid detection kit for total phosphorus water quality is based on the molybdenum blue colorimetric method. Phosphate packaging testing can easily measure phosphate concentration from samples such as industrial wastewater. The phosphate packaging test can only measure dissolved PO43- ions. Concentrated phosphorus or total phosphorus cannot be measured. Measurement of these parameters requires preprocessing. 2. This packaging test can simultaneously measure phosphate ions (PO43-) and phosphate ions (PO43-P). 3. The normal pH range is 2-9. If necessary, adjust the pH of the hydroxide solution with dilute sulfuric acid or sodium.

Detection method:
Notes:
1. The phosphate packaging test can only measure dissolved PO43- ions. Concentrated phosphorus or total phosphorus cannot be measured. Measurement of these parameters requires preprocessing.
2. This packaging test can simultaneously measure phosphate ions (PO43-) and phosphate ions (PO43-P).
3. The normal pH range is 2-9. If necessary, adjust the pH of the hydroxide solution with dilute sulfuric acid or sodium.
4. After adding phosphate, the reaction color is stronger than 10mg/L and the standard color is 1000mg/L. Expected high concentration sample water should be diluted in advance.
5. Ensure that the filling test tube is half filled.
6. Partially undissolved reagents will not affect the measurement.
7. Maintain the sample temperature within the range of 15 ° C to 40 ° C. The lower the temperature, the longer the reaction time.
8. Read the test under fluorescent light.
9. After use, place the pipeline back into the hole to prevent reagent overflow.
