Comparison of the photoactivities of two commercial titanium dioxide powders in the degradation of 1,4-dioxane
Two different commercial photocatalysts, Degussa P25 and Hombikat UV 100, were used to degrade 1,4-dioxane photocatalytically in an annular slurry photoreactor. The optimum photocatalyst loading for Degussa P25 was found to be 1.5 g L-1 while for Hombikat UV 100 was between 3.0−4.0 g L-1. The photoa...

| Summary: | Two different commercial photocatalysts, Degussa P25 and Hombikat UV 100, were used to degrade
1,4-dioxane photocatalytically in an annular slurry photoreactor. The optimum photocatalyst loading
for Degussa P25 was found to be 1.5 g L-1 while for Hombikat UV 100 was between 3.0−4.0 g L-1. The photoactivity
of Degussa P25 is higher than that of Hombikat at lower photocatalyst loadings whereas it is lower
at higher photocatalyst loadings. This was found both experimentally and also by mathematical modeling of
the radiation within the photoreactor zone. The photoactivity of UV 100 titanium dioxide was found to be
twice that of Degussa P25 at optimum loadings. |
