Chlorine Dioxide-Test

 

1. PrincipIe:

 

In weakly acidic solution chlorine dioxide reacts with dialkyl-p-phenylene diamine(DPD) to form a red violet dye. The concentration of Chlorine dioxide is measured semiquantitavely by visual comparison of the colour of the measurement solution with the colour fields of the colour card.

 

2. Chemical Reaction:

 

Cl02 + R1 + R2 ===> Red - Violet (Dye)

  3. Measuring range and number of determinations:
 

Measuring range / colour scale graduation
