Photocatalytic degradation of acetamiprid in a rotating photoreactor - determination of reactive species

In this work, the photocatalytic degradation of acetamiprid under UV-A light was studied in a rotating photoreactor operating in recirculated batch mode and using an immobilized layer of a modified TiO2 photocatalyst. The aim of the study was to determine the reactive oxygen radicals and to investigate the influence of interfering compounds, which are crucial for the successful photocatalytic degradation of acetamiprid. Superoxide anion radicals and singlet oxygen play a crucial role in the photocatalytic degradation mechanism of acetamiprid. In the presence of low concentrations of hydrogen peroxide, the degradation of acetamiprid is significantly enhanced.
