Zero-valent iron (ZVI) Fenton oxidation of reactive dye wastewater under UV-C and solar irradiation

摘要

In the frame of this work, photo-Fenton processes using the zero-valent iron (ZVI) as a catalyst have been applied for mineralization and decolourization of the model wastewater containing reactive azo dye, CI. Reactive Black 1 (RB1). Experiments were performed in the enhanced configuration of laboratory cylindrical batch photoreactor under UV-C irradiation (CBPR) and the boat-shaped flow reactor (BSFR) in total recirculation mode, exposed to direct sunlight, both with the immobilized iron.
