Abstract

A recycling open channel reactor was utilized for removal of organic contaminant of malachite green with flow rate of 5 mL/min. TiO2 nanoparticles and FeSO4 powder immobilized on metal-foam (MF) were applied as a photo-Fenton catalyst. Glucose oxidase (GOx) was also coupled with catalyst for in-situ generation of hydrogen peroxide. Furthermore, UV (6 W) lamp was used as a light source to carried out photo-bio-Fenton reaction in the reactor. Several experiments were carried out to study the influence of various combination of affecting processes on decolorization of the pollutant. Removal of 84.37% of malachite green was obtained in GOx/TiO2/Fe2+/MF process under UVA-LED during 20 min. © 2016 Taiwan Institute of Chemical Engineers
