GB/T 6912-2008 Analysis of water used in boiler and cooling system—Determination of nitrite
Abstract
This standard specifies the methods for determining the nitrite content in raw water, boiler water, and cooling water. In this standard, the molecular absorption spectrophotometry method is suitable for determining the nitrite content in raw water, boiler water, and cooling water ranging from 0 mg/L to 0.25 mg/L; the ultraviolet spectrophotometry method is suitable for determining the nitrite content in raw water, boiler water, and cooling water ranging from 0 mg/L to 25 mg/L.
