Arsenic Test Kit

Procedure: Small amount of sample is collected in a test tube and the corresponding reagent is added to the sample. Color of the sample changes and the same is compared with the respective color chart. The reading of the matched color on the color chart is the concentration of the respective parameter in the water.

Inorganic Arsenic compounds in the water sample are converted to Arsine (AsH2) gas by the reaction of Zinc Dust and Tartaric Acid. Ferrous and Nickel salts have been added to accelerate this reaction. The Arsine converts the Mercuric Bromide on the test strip to mixed Mercury halogens (such as AsH2 HgBr) that appear with a color change from white to yellow or brown. (Lead acetate cotton ball is used to remove the Hydrogen sulfide (H2S) interference).
