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

Figure 3

Laser flash photolysis at 355 nm in aerated aqueous solution at pH = 4.0 (a) Fe (OH)²⁺, alone at a concentration of 3×10⁻⁴ moL L⁻¹; 𝜆_detection = 360 nm. (b) Mixture Fe(OH)²⁺/fenamiphos (3.0×10⁻⁴ moL L⁻¹/3.5×10⁻⁴ moL L⁻¹); 𝜆_detection = 390 nm. The fitting was obtained using a monoexponential kinetic equation.
