Testing for Nitrite in the Presence of Glycol (K-1510)

Specifications

Sodium nitrite-base treatments are commonly used to establish a protective film on ferrous metal surfaces in closed cooling water systems and boilers. Cooling water may contain sodium nitrite as high as 1000 ppm, while boiler water may contain up to 1500 ppm.

To reduce treatment program costs, nitrite is often blended with molybdenum in closed cooling water systems. Taylor offers a molybdenum test (K-1805 or K-1805P) for monitoring these systems, but users should be aware levels of nitrite over 800 ppm may negatively interfere with the molybdenum test. In these cases, dilute the sample with demineralized water that is molybdenum- and nitrite-free. Alternatively, you can test the nitrite residual instead, using the K-1563.

Taylor's drop-count and buret titrations for monitoring sodium nitrite use either the permanganate method or the ceric oxidation of nitrite method (commonly called the "CAN" method). In cooling systems treated with glycol antifreeze, the "CAN" method must be used to prevent test interference.

This kit uses the ceric oxidation of nitrite method.

User Benefits

• Titrations do not require the ability to match colours, only the ability to see the permanent colour change at the endpoint of the reaction.
• Test kits come complete with all necessary reagents and equipment; reagent packs contain an instruction and reagents only.
• These test kits are practical for both on- and off-site testing.
• Waterproof instructions are printed on plastic-impregnated paper that resists fading and tearing.
• Picture guides to colour transitions in the test reassure new users.
• Custom-molded, durable plastic cases provide safe storage for all tests.
• Proven chemistries are based on Standard Methods for the Examination of Water and Wastewater, APHA, Washington, DC, and/or American Society for Testing and Materials, ASTM, Philadelphia, PA. Some methods use proprietary chemistry developed by Taylor Technologies.
