ITEM #: 4184858
Nitrite, an intermediate in the nitrogen cycle, is formed during the decomposition of organic matter but readily o x idizes to form nitrate. These processes occur in wastewater treatment plants, water distribution systems, and natural waters. Nitrites are useful as corrosion inhibitors, preservatives, pigments, and in manufacturing many organic preservative chemicals. A Ma x imum Contaminant Level of 1 mg/L has been established by the USEPA for nitrite-nitrogen in drinking water.

Azo Dye Formation Method
References: APHA Standard Methods, 22nd. ed., Method 4500-NO 2 -? B - 2000. USEPA Methods for Chemical Analysis of Water and Wastes, Method 354.1 (1983).
Nitrite diazotizes with a primary aromatic amine in an acidic solution to produce a highly colored azo dye. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Nitrate will not interfere. Results are e x pressed as ppm (mg/L) NO 2 -N.
Range: 0-2.5 ppm as N
MDL: 0.2 ppm
Method: Azo Dye Formation
Kit comes in a plastic case and contains everything needed to perform 30 tests: Refill, Comparator, 25 mL sample cup, and instructions.
WARNING! This product can e x pose you to chemicals including ethylene glycol, which is known to the State of California to cause birth defects or other reproductive harm. For more information go to .
