Chromium is a common and toxic heavy metal, among which hexavalent chromium is particularly harmful to human health and the environment due to its easy absorption by organisms. Hexavalent chromium can invade the human body through mucous membranes such as the digestive tract, respiratory tract, and skin. When entering the human body through the respiratory tract, it can cause damage to the nasal mucosa, and in severe cases, it may cause nasal septum perforation and bronchiectasis; When invading the digestive tract, it can cause vomiting and abdominal pain; Invasion through the skin can cause dermatitis and eczema; It is also a type of strong carcinogen.

Due to the hazards of hexavalent chromium, the country has classified it as a Class I water pollutant, with strict limits in industrial wastewater, environmental water, and other standards. At the same time, the European Union, China, and other countries have also set limits on the presence of hexavalent chromium on the surface of products such as electroplating, hardware products, and electronic components. To eliminate the tedious operation of preparing reagents and testing processes for users, and improve detection efficiency, this product is launched based on the diphenylcarbazide (DPC) spectrophotometric method (GB/T 5750.6-2006)Water quality hexavalent chromium detection reagent.

Diphenylcarbazide (DPC) spectrophotometric method (GB/T 5750.6-2006). DPC reagent reacts with hexavalent chromium to produce a purple red color, and the depth of the color is proportional to the content of hexavalent chromium.

Water quality hexavalent chromium detection reagentTesting precautions

1. 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;

2. This reagent is a white or light pink powder. If there is a significant change in the properties of the reagent, please stop using it and contact the manufacturer;

3. The color or turbidity of the water sample to be tested may interfere with the test, and coexisting oxidants or reducing agents may interfere with the measurement;

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