2. Feature

Quick and easy

Users can complete the analysis of the residual concentration of ClO₂ in water independently without specialized training. Five minutes is enough to complete the analysis of one sample. small size and light weight, specially designed for on site testing.

Accurate and reliable

This method equals to the on-site testing of chlorine dioxide method (GB/T5750-2006). The chlorine dioxide in water samples reacts with N, N-diethyl-p-phenylene -diamine (DPD) to produce a kind of pink compound. 20% chlorine in chlorine dioxide converts into chlorite. The chromogenic reaction is proportional to the content of chlorine dioxide in water.

3. Operation

2. Add four drops of ClO₂ (I), Cap and shake to mix. Add one DPD NO.3 tablet immediately, Cap it and compare the color visually just after dissolved.

4. Put the colorimetric tube on the blank of the standard card, then lift the tube up to 1cm, observe the color in the tube from top to bottom, find out the same level on the standard card.

Note:

(1) If the alkalinity is more than 250mg/L, or the acidity is more than 150mg/L, the generating of the color will be restrained or the color will fade.
(2) The presence of bromine, chlorine, iodine, ozone, 1-chlonoamine, manganese, chromium, organic amines, peroxides and other oxidant will affect the result.
(3) The color will be stable for 5min.

Chlorine dioxide (ClO₂), which has been recognized as efficient, broad-spectrum and belong to the security of AⅠ-level, is a new type of disinfector widely used in drinking water disinfection, microbial control for food safety and other fields. In order to push the application of ClO₂and meet the requirements of monitoring of environment, the research on test methods of the working concentration and the residual concentration of ClO₂ is subject to attention increasingly.
