Description
Photometric determination of total nitrogen.
• Oxidative decomposition in the heating block with subsequent interference compensation
and photometric determination with 2,6-dimethylphenol in sulphuric acid / phosphoric acid mixture.
• All organic and inorganic nitrogen containing substances are oxidised to nitrate in acidic solution.
In acidic solution nitrate ions react with 2,6-dimethylphenol to form 4-nitro-2,6-dimethylphenol,
which can be evaluated photometrically.
