Tested Sample Types: Water
Assay Time: 50 min
Detection Type: Colorimetric method
Sensitivity: 0.2 μmol/L
Detection Range: 0.2-100 μmol/L
Test Principle: Hexavalent chromium ion (Cr6+) is a highly toxic and harmful substance, which is a great threat to human health and environmental pollution. The Cr6+ pollution in the environment mainly comes from the wastewater and waste gas discharged by industries such as electroplating, leather, and metallurgy. Substances containing Cr6+ have a strong irritant effect and high permeability on the skin, which can cause damage to the cardiovascular and hematopoietic functions of the human body, and lead to diseases in organs such as the liver, kidney and lung.
The detection principle of this kit is as follows: Cr6+ can react with the chromogenic agent under acidic conditions to produce a purple-red substance, with the maximum absorption at a wavelength of 540 nm. The content of Cr6+ in the water sample is calculated by measuring the OD value at 540 nm.
