Ozone Oxidation Accelerator, Ozone Oxidation Accelerator Composition, and Ozone Treatment Method

Abstract

The present invention relates to an ozone oxidation accelerator containing a compound of which a 0.5% by mass aqueous solution at 25° C. has a dynamic surface tension at 100 msec of 70 mN/m or less and a dynamic surface tension at 30 sec of 55 to 67 mN/m, and an ozone oxidation accelerator composition containing the ozone oxidation accelerator. The present invention also relates to an ozone treatment method including a step of supplying ozone into water to be treated that contains a substance to be treated, in the presence of the ozone oxidation accelerator composition.
