The photocatalyic degradation of N-Methyl-2-pyrrolidone, NMP, was investigated in an aerated UV-Vis/TiO2 system. The effects of catalyst loading, temperature and pH on the reaction rate were ascertained. The result showed that the photocatalytic degradation of NMP was strongly influenced by these parameters and the optimum condition for maximum degradation was determined.
