Photocatalysis: Oxidative Processes in Water Treatment
Figure 5
The dependence of the initial velocity () of DCPA photocatalytic oxidation by atmospheric oxygen on initial concentration of the DCPA () in the aqueous suspensions Fe2O3 (0,5 wt.%)—TiO2 (1), TiO2 (2), and Fe2O3 (3) a composite system based on in water (pH 4.5) (a); photo generation of H2O2 in aqueous suspension Fe2O3 (1 wt%)—TiO2, (1 g μM−3) in an oxygen atmosphere under UV light (high-pressure mercury UV lamp SVD-120, 380–400 nm) at pH: 1–6.0; 2–3.0; 3–9.0 (b).
