LCK391 AOX cuvette test 0.005 - 0.5 mg/L

Description

Cuvette test for the determination of AOX (adsorbed organohalogen compounds) from Hach.

Reagent kit LCK391 for photometric determination of adsorbed organic halogens. Complies with DIN EN ISO 9562.

The pH of the water sample should be between 4 and 9.
The temperature of the water sample and reagents should be between 15-25 °C (59-77 °F).

Applications: For waste water, service water, drinking water and surface water.

Method description: organic halogen compounds, which are present in water in dissolved form, are adsorbed by activated carbon due to their hydrophobic properties. Then the activated carbon is burned with oxygen. This frees the halogen atoms from the adsorbed organic halogen compounds in the form of hydrogen halides. They form halogen acids, which are involved in the color reaction in the cuvette test, and this is measured photometrically. AOX concentration is usually expressed in μg/L chloride, as chlorine is the most abundant halogen in organic halogen compounds.
