Significance and use
In pools and drinking water supplies, chlorination serves to
kill or deactivate disease-producing microorganisms. It can
also improve water quality by reacting with ammonia, iron,
sulfide and some organic substances. However, an excessive
concentration of chlorine in water can produce adverse
conditions, such as formation of carcinogenic chloroform or
other toxins. To maximize the purpose for chlorination and
minimize any adverse effects, it is essential to monitor the
chlorine levels closely.
The Hanna Chlorine Test Kit determines the Free chlorine
concentration in water via a color cube. This makes the test
kit practical for field use. No iodine or bromine can be
present for this test to work properly.
Chemical reaction
The addition of chlorine to water produces hydrochloric and
hypochlorous acids. The hypochlorous acid acts as the
disinfectant and bleaching agent. These are known as free
chlorine, which is measured by a colorimetric method. The
reaction is buffered at approximately 6.3 pH; in that
condition DPD (N,N-diethyl-p-phenylenediamine) is
immediately oxidized by chlorine producing a reddish color.
The color intensity of the solution determines the free
chlorine concentration.
Instructions
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Add 5 drops of Reagent 1 and 3 drops of Reagent 2 to
the color comparator cube.
• Fill the color comparator cube with water sample to the
5 mL mark.
• Replace the cap and mix by carefully swirling the cube
in tight circles and inverting it several times.
• Determine which color band best matches the solution in
the vessel and record the results in mg/L (ppm) free
chlorine.
