Abstract

This study investigates the effects of a voltage swing interval on 1,4-dioxane decomposition in aqueous media. The concentration of 1,4-dioxane decreases with the decreasing voltage swing interval, but the change is small. In contrast, the concentration of EGDF increases with the decreasing interval. Its difference is much greater than that of 1,4-dioxane. These results suggest that the diffusion constant of EGDF in a pore structure differs from that of 1,4-dioxane and that the response to the voltage swing interval depends on the chemical species. For effective water purification using this system, proper material design and optimization of operation conditions are necessary.
