Characterization and Evaluation of the Efficiency of TiO2/Zinc Phthalocyanine Nanocomposites as Photocatalysts for Wastewater Treatment Using Solar Irradiation
Figure 6
Degradation of the organic load present in 50 L of an aqueous
model-effluent containing LSA (160 mg/L). Reactions done proceeded at pH 3,
using 100 mg of catalyst per liter of effluent, and addition of 1.00 mL of
hydrogen peroxide per liter of
effluent. Effluent treated using: (1) pure TiO2; (2) TiO2/ZnPc
2.5% composite; (3) a recycled TiO2/ZnPc 2.5% composite; (4) TiO2/ZnPc
2.5% in its second recycle. Inset: Pseudofirst-order
rate profiles for the effluent degradation under the above mentioned
conditions.
