Colorimetric Procedure

The objective is to maintain a hydrazine residual between 0.05-0.2 ppm depending on operating pressure and boiler designe. Actual consumption is determined under operating conditions.  A normal dosage is approximately 1 ltr. per day, depending of system layout.

Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. Thus, it is used as an ANTIOXIDANT, an oxygen scavenger, and a corrosion inhibitor in water boilers and heating systems. 

Hydrazine is mainly used as a foaming agent in preparing polymer foams. 

No oxygen is entering the boiler with the feed water when hydrazine is present in the water.

Application

Directions for use : Based on Colorimetric Procedure
1. Take 5 ml of sample to be tested in the Test jar ( Before testing, samples must be cooled to 25oC by passing them through a cooler.). if necessary. Turbid samples are to be filtered with a filter paper.

2. Add 40 drop (2ml) of Reagent TK-16. Mix wel
3. Add 2 micro spoon full of Reagent TK-17. Mix well upto provider dissolves Completely. Wait for 10 minutes.
4. Now rinse the empty comparator tube with above solution and will upto the half level of the comparator tube.
5. Insert this tube in sample slot of comparator.
6. Compare the developed colour with standard comparator colours. Slide the comparator until the colors match. Check the mea- surement reading in the recess on the comparator reed. Mid values can be estimated
7. Note down the ppm level of Hydrazine as N2H4
8.After use, rinse out both measuring glasses thoroughly and seal them.

Note 1 ::: Studies showed that hydrazine was not stable on the sampling device, therefore, immediate extraction of samples after collection was recommended. 

Note 2 ::: color is stable for 1 hours.

Sample of Hydrazine is Harmful. Handle with due care.

All open chemicals should be used only in a fume hood.

Avoid any skin contact with all chemicals. Immediately flush contaminated areas with copious amounts of water.

Wear safety glasses at all times.
