| Research Abstract |
The value of gas-liquid equilibrium coefficient, which shows ozone dissolution extent, has been discovered to decease under higher concentration of chloride ion than around 20 g/L which corresponding to sea water level. This phenomenon causes to decrease degradation rate of organic substances. 1,4-dioxane can be effectively degraded by advanced oxidation process (ozone-hydroperoxide). Inactivation effect on sea water microorganisms is also shown.
