fotokataliza - Opis:
- A slurry UVA-LED concentric glass tube reactor (CGTR) with micro-depthof 2 mm was designed for plug flow behaviour (length/effective diameter = 150). The reactor design considered uniform radial concentration and hydrodynamic cavitation. The 100% Acridine Orange dye (3.77×10-5 M) was removed within 35 min at the graphene oxide dose of 0.3 g/dm3 and initial pH 11. It was observed that hydrodynamic cavitation shortened the reaction time and enhanced the apparent reaction rate constant from 0.022 to 0.109 min-1. Further, the degradation pathway showed that decolourized dye solution consisted of ethylenedione (34%), indicating the oxidative reaction occurred.
