Chlorine / Chlorine dioxide
Chlorine (Cl2) and chlorine dioxide (ClO2) are important chemicals for water purification, in disinfectants, and in bleach. They are used as biocides in many industrial water treatment applications including cooling towers, process water and food processing.
Chlorine dioxide has a strong absorption between 350 and 500nm that the Kemtrak DCP007 LED process photometer can measure – from ultra low parts per million concentrations when used for gas detection or disinfection, to high concentration solutions used for the bleaching of pulp (>10 g/L).
The Kemtrak DCP007 LED process photometer can be used to optimize the reaction efficiency of ClO2 generation, improve the control of vent-gas scrubbers to reduce emissions into the atmosphere and for monitoring the final concentration of chlorine dioxide product sent to the bleaching plant.
Chlorine dioxide is an aggressive chemical substance – all wetted parts of the Kemtrak measurement cells are manufactured from corrosion resistant materials, such as PTFE, titanium, hastelloy, monel and sapphire.
