Used in low pressure and auxillary boilers
:::::::::::::::::::::Alkalinity TEST FOR BOILER & COOLING WATER ::::::::::::::::::::::::
REAGENT & APPARATUS :
Reagent: RXSOL TK 7 , TK 8 , TK 9 , . Apparatus : TEST TUBE , Titrator or DROPPER
PROCEDURE for p-ALKALINITY test ( STEP WISE ):
- Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
- 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 ) .
- 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 Alkalinity .
NOTE : p-Alkalinity VALUE = 25 X ( Total Number of DROPS of TK9 , during 3rdstep )
PROCEDURE for p-ALKALINITY & TOTAL ALKALINITY ( STEP WISE ):
- Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
- 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 ) then proceed to STEP- 4.
- 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
- Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .
- AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish pink colour develop.
RESULT : Each DROPS is equivalent to 25 PPM of Alkalinity .
NOTE : p-Alkalinity ppm CaCO3VALUE ( A ) = 25 X ( Total Number of DROPS of TK9 , during 3rdstep )
Total Alkalinity ppm CaCO3VALUE = A + { 25 X ( Total Number of DROPS of TK9 , during 5th step )}
NUMBER OF DROPS OF TK9 p-Alkalinity as CaCO3
1 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>25
3 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 75
5 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > 125
20 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > 500
40 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 1000 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-50-5001-020for 1000 Ltrs of BOILER WATER , to maintain p-Alkalinity level 100 ppm.
