TiO_𝟐 Photocatalysis of the Organophosphorus Fenamiphos: Insight into the Degradation Mechanism

Figure 4

Observed rate constant, 𝑘_obs, for the formation of the adduct ^•OH-FN obtained from the laser flash photolysis traces at the detection wavelength 390 nm at various concentrations, X, of fenamiphos. Excitation at 355 nm; mixture Fe(OH)²⁺/fenamiphos (3.0×10⁻⁴ moL L⁻¹/X moL L⁻¹), pH = 4.2.
