Background of development
Chlorine dioxide (ClO2), which has been recognized as efficient, broad-spectrum and belong to the security of A-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.
Principle:
This method equals to the on-site determination 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.
The features of the product:
Quick and easy
Operating in accordance with the instructions, 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.
Accurate and reliable
Determination results with this method are in accordance with the results with the standard method. It can be used as an alternative method to the standard method.The range of the determination: 0.05mg/L~2.0mg/L, if the concentration is out of range, please repeat the operation after appropriate dilution of the sample.
Quantitative packingThe kit can be used for 50 times. It is small, light and easy to carry.
Specification
1. Fill the round sample cell with 15ml of sample.
2. Add four drops of ClO2 (I), Cap and shake to mix .
3. Add one DPD NO.3 tablet immediately, Cap it and compare the color visually just after dissolved.
4. Put the colorimetric tube to 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 in the standard card. The concentration (mg/L) level of the standard card that has the same color as the sample shows the concentration of chlorine dioxide of the sample.
