Frantz Paul apparatus - Determination of SO2

Sulphur dioxide extraction by aeration/oxidation

The determination of free and total SO2 by distillation/oxidation is based on the use of a Frantz Paul apparatus, whose different parts must respect specific characteristics such as shape, materials and dimensions. This is the only method considered as a reference by the OIV.

PRINCIPLE

SO2 is extracted by gas in acid condition (air or nitrogen). It is fixed and oxidized in the bubbling flask, containing a diluted and neutralized solution of hydrogen peroxide. The sulphuric acid formed is titrated by a standard solution of sodium hydroxide (titration accessories not included). The free SO2 is extracted from a cold sample, while total or combined SO2 requires a heating of the sample.
