Hydrogen peroxide water quality detection reagentIt eliminates the tedious operation of preparing reagents and testing processes for users, improves detection efficiency, is easy and fast to operate, and has low testing costs. Hydrogen peroxide is a widely used oxidant. Uses include: treating industrial wastewater and municipal sewage, disinfectants in sterile packaging, etc.

Hydrogen peroxide water quality detection reagentIn the presence of a catalyst, peroxide reacts with DPD to form a red complex. By measuring the absorbance value of the colorimetric solution at a wavelength of 525nm, the hydrogen peroxide content in the water sample can be obtained. Within a certain concentration range, the absorbance value is directly proportional to the hydrogen peroxide content in the water sample.

Testing precautions

1. For more accurate testing, the reagent blank value should be measured every 3 months. The determination of reagent blank is also carried out according to the testing steps, except that the sample is replaced with pure water for testing. Subtract the blank value of the reagent from the final test result;

2. If the content is higher than the reagent range, the measured value can only be used to estimate the dilution factor and cannot be used as a test result. After diluting the sample, retest;

3. The powdered reagent is a white or light gray powder. If the reagent clumps or turns black, please stop using it and contact the manufacturer;

4. The pH value of the water sample to be tested is 5.0-8.0;

5. The measurement should be completed within 4 minutes after the completion of color development. Prolonged time will result in inaccurate test results;

6. The triangular positioning mark on the colorimetric tube should be aligned with the positioning mark on the instrument during zeroing and reading;

7. If the water sample contains oxidizing substances such as residual chlorine, total chlorine, and high valence manganese ions, it will cause positive interference;

8. Store in a dry, cool place, out of reach of children. Do not store with food, medicine, etc., and do not put into fire.
