Titanium Dioxide-Mediated Photcatalysed Degradation of Two Herbicide Derivatives Chloridazon and Metribuzin in Aqueous Suspensions

Figure 4

Effect of initial herbicide concentration on the degradation rate. Experimental conditions: Herbicide concentration: CHL (0.14, 0.16, 0.18, and 0.20 mM), MET (0.24, 0.27, 0.30, and 0.33 mM), 𝑉=125 mL, photocatalyst: TiO₂ Degussa P25 (1 gL⁻¹), irradiation time: 60 min (CHL), 28 min (MET).
