The oxidation proceeds through a combination of path-
ways to varying degrees for both photocatalysts. Direct
oxidation of the contaminant as well as OH radical attack
appears to be an important contributor to the degradation
by the polyoxometalate. Further oxidation of succinimide in

degradation appears to be an effective method for oxidative
destruction of NMP contaminants (and in general, nonaro-
matic organic substances) in wastewater, with TiO being

the more efficient photocatalyst as also illustrated by our
previous work with 2-propanol (42). However, the utilization
of an additional significant degradation mechanism (i.e.,
direct oxidation) by the tungstate may make it an attractive
