Oxydation de solutions d’acide iodhydrique par l’air en présence de lumière
The reaction 4 HI + O2 →hν 2 H2O + I2 has been studied as a possibility of regeneration of the cathodic fuel in a cell using the cathodic reaction I2 + 2 e- → 2 I-. The influence on the rate of reaction of the following factors has been quantitatively investigated: - iodide, oxygen, and acid conc...

| Summary: | The reaction 4 HI + O2 →hν 2 H2O + I2 has been studied as a possibility of regeneration of the cathodic fuel in a cell using the cathodic reaction I2 + 2 e- → 2 I-. The influence on the rate of reaction of the following factors has been quantitatively investigated:
- iodide, oxygen, and acid concentrations,
- light intensity,
- ratio surface / volume of the cylindrical reactor
An equation allowing the computation of the rate of iodine formation under various conditions is proposed. – Wave length of the incident light and temperature are other parameters influencing the rate of oxydation.
