Product code RXSOL-62-5507-001
Nitrites are useful as corrosion inhibitors, preservatives, pigments, and in manufacturing many organic preservative chemicals. A Maximum Contaminant Level of 1 mg/L has been established by the USEPA for nitrite-nitrogen in drinking water.
::Very simple 3 step procedure ::
Applications and Industries: Industrial process waters, boiler water, cooling waters
Chemistry: Results are expressed in ppm (mg/L) sodium nitrite (NaNO2).
Application
The method is free from glycol interference in samples that contain up to 75% glycol, making it particularly applicable to systems that contain nitrite corrosion inhibitors. Results are expressed as ppm (mg/L) NaNO2.
Dosage
PROCEDURE for test ( STEP WISE ):
- Measure 1 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER , with the help of syringe / pippet and diluted with Distilled Water up to 10 ml.
- Add 1-2 drops of RXSOL TK5 and mix with the stirring rod , to obtain ORANGE / light reddish colour.
-
Add RXSOL TK6 drop by drop , mixing with the stirring rod until For endpoint ORANGE to BLUE / GREENISH colour just appears / develop.
Each DROPS is equivalent to 50 PPM of NO2
CALCULATION : 50 X Number of DROPS of TK6
