Free Chlorine

Test Kit

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.

SIGNIFICANCE AND USE

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 immedi-

ately 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.
