Volatility of HOI
Description
The volatility of HOI has been measured using a mass spectrometer to analyze the gas phase above an aqueous solution. The HOI in solution was generated continuously in a flow reactor that combined I- and OCl- solutions. The analysis has resulted in a lower limit of 6 x 103 mol.dm-3.atm-1 for the equilibrium constant for the reaction HOI(g) in equilibrium HOI(aq). This value is a factor of 30 greater than the best previous estimate. This new limit for HOI volatility results in higher total iodine partition coefficients, particularly for solutions with pH > 8. The upper limit for the equilibrium constant is consistent with essentially zero volatility for HOI. The effect of HOI volatility on total iodine volatility is briefly discussed as a function of solution chemistry and kinetics
