(1) Luɔi: DEK-1001 COD online water quality analyzer measuring method uses national standard GB11914-89 water quality-chemical oxygen requirement measurement (potassium chromate method). Pii, potassium dichromate, silver sulfate (catalyst makes straight chain fatty acids oxide more fully) and concentrated sulfuric acid mixture are heated to 175°C in the dissolution pool, during this period chromium ions as an oxidant were reduced from VI value to III value and changed colour, the colour change degree corresponds to the content of organic compounds in the sample, and the instrument displays the COD of the sample directly through color conversion.
