| 摘 要： | In this paper, a method for TiO2 supported on hollow glass microbeads was described and the feasibility of photocatalytic degradation of dichlorvos using supported TiO2(TiO2/beads) was studied. The results showed that 1.0×10-4 mol.dm-3 of dichlovos could be completely photocatalytically degraded into PO43- after 120 min illumination with a 375 W medium pressure mercury lamp. The effects of the amount of TiO2/beads and concentration of Cu2+ on the photocatalytic degradation were also investigated. Some intemediate products of photocatalytic degradation of dichlorvos were detected. |
