Introduction
Monitoring persulfate levels in water is essential across various industries, from environmental cleanup to pool maintenance. The CHEMetrics K-7870 Persulfate Kit offers a reliable and user-friendly solution for measuring persulfate concentrations in water, providing both low (0-5.6 ppm) and high-range (7-70 ppm) measurement capabilities. With its innovative design, easy-to-use ampoules, and rapid results, this kit stands out as a powerful tool for accurate testing.
Why Choose CHEMetrics Chemets Kits?
CHEMetrics Chemets self-filling reagent ampoules are engineered for convenience, precision, and safety. These kits enable you to measure dissolved substances in liquids visually, using a color comparison method. By simply observing the color intensity of the sample in comparison to the provided color standards, users can quickly obtain results with minimal handling of chemicals. Here’s why CHEMetrics Chemets kits have become a preferred choice for professionals:
- Quick and Accurate Results: The color comparator method offers rapid feedback on persulfate levels, allowing users to gauge concentrations within moments.
- Minimal Contact with Chemicals: Each reagent is vacuum-sealed in a glass ampoule, reducing exposure to potentially hazardous materials and ensuring operator safety.
- Easy Operation: Designed with simplicity in mind, Chemets kits reduce steps, lowering the risk of user error while providing consistent, reliable results.
Safe and Reliable Testing
Traditional methods for measuring dissolved substances often require extensive preparation, multiple reagents, and careful handling. The CHEMetrics Chemets kits streamline this process significantly. Each self-filling ampoule is vacuum-sealed to maintain the stability of the reagents, which ensures that your results remain reliable and unaffected by exposure to air or environmental contaminants. By having the reagent stored in the tip of each ampoule, you get fresh, stable chemicals every time without the hassle of mixing or preparation.
What’s Included in the K-7870 Persulfate Kit?
The K-7870 Persulfate Kit comes with everything needed for convenient and accurate testing:
- 30 Self-filling Ampoules: Each ampoule is pre-loaded with the precise amount of reagent.
- Low and High-Range Color Comparators: Color standards for both 0-5.6 ppm and 7-70 ppm ranges.
- 25 mL Sample Cup: Used to hold the water sample for testing.
- Instruction Manual: Provides detailed step-by-step guidance on how to perform the test.
How Does the K-7870 Kit Work?
The K-7870 Kit uses the Ferric Thiocyanate Method to measure persulfate concentration. In an acidic solution, persulfate oxidizes ferrous iron, creating a ferric ion. This ion reacts with ammonium thiocyanate to form ferric thiocyanate—a red-orange colored complex that reflects the persulfate concentration in the sample. Because the color intensity corresponds to the persulfate level, users can determine the concentration by matching the ampoule’s color to the provided comparators. Notably, the test chemistry is chlorine-resistant, though it may be influenced by ferric iron, hydrogen peroxide, and ozone.
Step-by-Step Guide to Using the K-7870 Persulfate Kit
Using the K-7870 Kit is straightforward:
- Fill the Sample Cup: Fill to the 25 mL mark with the water sample.
- Activate the Ampoule: Place the ampoule tip-first into the sample cup. Snap the tip, and it will automatically fill.
- Mix the Sample: Tilt the ampoule back and forth, allowing the bubble to travel through the liquid for thorough mixing.
- Wait for Color Development: Dry the ampoule and wait 1.5 minutes for the color to develop.
- Compare the Colors: Place the ampoule into the center of the round comparator, view from the bottom, and rotate to find the closest color match.
- Use the Flat Comparator for Higher Concentrations: For concentrations above 5.6 ppm, use the flat comparator by placing the ampoule along the color standards to find the best match.

Applications of Sodium Persulfate
Sodium persulfate is widely used as a potent oxidizer in applications like:
- Pool and Spa Maintenance: For water clarity and as a bleaching agent.
- Environmental Cleanup: Effectively degrades a wide range of soil and groundwater contaminants.
Safety Note: P6508
Warning: This kit contains methanol, which the State of California recognizes as a chemical known to cause birth defects and reproductive harm. Please follow all safety guidelines and wear protective equipment when using this product.
Conclusion
The CHEMetrics K-7870 Persulfate Kit provides a convenient and reliable method for measuring persulfate levels with accuracy and minimal handling of chemicals. Its user-friendly design, quick results, and high-precision ampoules make it a valuable tool for industries that require accurate water analysis. If you’re looking for an efficient, safe, and easy way to monitor persulfate, the K-7870 is an excellent choice.
