BOILER WATER TEST KIT

Alkalinity Test Kit - RXSOL-62-5515-001

 

 
 

 

Alkalinity is the ability of inacitivate a known quantity of standard acids. Many commonly occurring materials, such as carbonate, bicarbonate, phosphates, and hydroxides, increase alkalinity in natural waters. Alkalinity is measured commonly by titration, using either a burette or the drop count technique.

Test of Alkalinity includes

  1. P- Alkalinity Test (CaCO3) - It warns the boiler rupture due to caustic content .Used to test alkalinity in sample for carbonates and hydroxides.
  2. M- Alkalinity Test- It warns against boiler rupture due to carbonic acids and steam condensate lines .Used to test alkalinity in sample for carbonic acids and bicarbonates.
  3. Total Alkalinity Test -

REAGENTS : TK7, TK8 & TK9

APPARATUS : Test Tube, Titrator and Dropper

Procedure : P- Alkalinity Test

  1. Add 1-2 drops of RXSOL TK 7 in 10 ml of water taken in a marked test tube. On stirring if the sample turns red or pink alkalinity is positive . If colourless alkalinity is negative.
  2. In positive condition add RXSOL TK 9 drop by drop (by counting) mixing with rod until sample turns colorless. (Each drop = 25 ppm of p-alkalinity / caco3)
  3. P- Alkalinity value 25 x total number of drops of RXSOL TK 9

Procedure : M- Alkalinity Test

  1. Add 2-3 drops of RXSOL TK 8 in 10 ml of water taken in a marked test tube. On stirring if the sample turns bluish green alkalinity is positive . If colourless alkalinity is negative.
  2. In positive condition add RXSOL TK 9 drop by drop (by counting) mixing with rod until it appears a light reddish pink color . (Each drop = 25 ppm of P-alkalinity / caco3)
  3. M- Alkalinity value25 x total number of drops of RXSOL TK 9

Total Alkalinity = P Alkalinity value + M Alkalinity value

Conclusion :

  • If P-Alkalinity is more than 150 ppm then level should be reduced by increased BLOWDOWN immediately .
  • If P-Alkalinity is less than 50 ppm level Doze half litre of RXSOL-50-5001 with 1000 ltrs of water to maintain the level upto 100 ppm
