Introduction
Welcome to the training session on using the Taylor Nitrite Test Kit for testing Sodium Nitrite in hydronic closed-loop water systems. Sodium Nitrite is commonly used as a corrosion inhibitor in these systems, forming a protective film on metal surfaces. Proper testing ensures the system remains protected and operates efficiently.
Components of the Taylor Nitrite Test Kit
The Taylor Nitrite Test Kit (K-1510) includes:
- Sample Tube: Graduated (25 mL) with cap
- Ferroin Indicator: 2 oz
- CAN Solution: 2 oz
Step-by-Step Procedure
- Preparation: Ensure all reagents are stored properly and are not expired. Keep reagents away from direct sunlight and extreme temperatures3.
- Sample Collection: Rinse and fill the sample tube to the 5 mL mark with cooled (room temperature) water from the system.
- Adding Indicator: Add 4 drops of Ferroin Indicator to the sample tube. Swirl to mix until the sample turns reddish-orange2.
- Adding CAN Solution: Add the CAN Solution dropwise, swirling and counting each drop until the color changes from reddish-orange to blue.
- Calculation: Multiply the number of drops of CAN Solution by 40 to get the concentration of Sodium Nitrite in parts per million (ppm).
Important Notes
- Safety: Handle all reagents with care and follow the precautions on the reagent labels.
- Accuracy: Ensure the sample tube is filled accurately to the 5 mL mark.
- Interference: Be aware that high levels of nitrite can interfere with other tests, such as the molybdenum test.
Conclusion
Regular testing of Sodium Nitrite levels in your hydronic closed-loop water system is crucial for maintaining system integrity and performance. The Taylor Nitrite Test Kit provides a reliable and straightforward method for ensuring your system remains protected from corrosion.
