Solubility of Iodine in Sub/Supercritical Carbon Dioxide

The solubility of iodine in sub- and supercritical carbon dioxide was studied using a flow-type extraction setup. It is shown that at 20—80 °C and 60—350 atm, the solubility of iodine increases at rising temperature and CO2 pressure and the mole fraction of iodine in its saturated solution ranges from 0,12 · 10-3 to 1,42 · 10-3.

Key words: iodine, solubility, carbon dioxide, subcritical conditions, supercritical conditions, iodometric analysis
