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
:::::::::::::::::::::Alkalinity TEST FOR BOILER & COOLING WATER ::::::::::::::::::::::::
REAGENT & APPARATUS | |||||||||||||||||||||||||||||||
Reagent: RXSOL TK 7 , TK 8 , TK 9 , . Apparatus : TEST TUBE , Titrator or DROPPER | |||||||||||||||||||||||||||||||
A.) PROCEDURE for p-ALKALINITY test ( STEP WISE ) | |||||||||||||||||||||||||||||||
1 |
Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER |
||||||||||||||||||||||||||||||
2 |
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 3rdstep otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) . |
||||||||||||||||||||||||||||||
3 |
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 |
||||||||||||||||||||||||||||||
RESULT | Each DROPS is equivalent to 25 PPM of p-Alkalinity. | ||||||||||||||||||||||||||||||
NOTE | p-Alkalinity VALUE = 25 X ( Total Number of DROPS of TK9 , during 3rdstep ) | ||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||
C.) PROCEDURE for TOTAL ALKALINITY ( VALUE of A + VALUE of B ) | |||||||||||||||||||||||||||||||
2.1 |
Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER |
||||||||||||||||||||||||||||||
2.2 |
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 3rdstep otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4. |
||||||||||||||||||||||||||||||
2.3 |
Add RXSOL TK9 drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 15 ppm of p-Alkalinity , expressed as CaCO3 |
||||||||||||||||||||||||||||||
2.4 | Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN . | ||||||||||||||||||||||||||||||
2.5 |
AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish ( salmon ) pink colour develop. |
||||||||||||||||||||||||||||||
RESULT | Each DROPS is equivalent to 25 PPM of Alkalinity | ||||||||||||||||||||||||||||||
NOTE |
p-Alkalinity ppm CaCO3VALUE = 25 X ( Total Number of DROPS of TK9 , during 2.3 step ) = X ( Say ) |
||||||||||||||||||||||||||||||
Optimum Result : p-Alkalinity level is between 100 to 150 PPM is suggested. if p-Alkalinity level is more then 150 ppm then level should be reduced by increased BLOW DOWN process with immediate effect. For Below 50 ppm , Dose ½ Ltrs of RXSOL-50-5001-BWT for 1000 Ltrs of BOILER WATER , to maintain p-Alkalinity level 100 ppm.
