Add RXSOL TK9 drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 25 ppm of p-Alkalinity , expressed as CaCO3
Add 1-2 drops of RXSOL TK7 and mix with the stirring rod , If sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 )
HYDRAZINE TEST POWDER TK-17
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.
