Target markets / Applications
• Drinking water control

General information
Arsenic is a semimetal that is known primarily for its toxicity. It can get into drinking water or plant foods through environmental influences.
The World Health Organization (WHO) classifies the international arsenic contamination of drinking water as massive. Therefore, wells are tested and marked as contaminated or uncontaminated. The tests can be done easily with QUANTOFIX® EZ Arsenic Sensitive PP test kit.

Reaction principle
The detection of inorganic arsenic(III) and arsenic(V) compounds in water samples is achieved by adding zinc powder and a solid acid. The released arsine reacts with the mercury(II) bromide of the test field and forms yellow to brown arsenic-mercury halides.
