The principle of the spectrophotometric method for volatile phenol in water online monitoring equipment is based on the color reactions between volatile phenols and specific reagents at specific wavelengths. Specifically, the equipment first preprocesses the water sample to remove interfering substances, then adds a phosphoric acid solution and heats it to boiling so that volatile phenols escape with the steam and condense for collection. Next, buffer and chromogenic agent (4-aminoantipyrine) are added to the colorimetric cell, which react with volatile phenol to form colored compounds. The absorbance of this colored compound is proportional to the content of volatile phenols.
