Comparative study using design experiment to assess an anionic dye degradation in aqueous solution through the application of different advanced oxidation processes

Abstract

This study aims to compare the anionic dye degradation (Titan yellow dye: DY9) in synthetic solution using three advanced oxidation processes, namely, Fenton process (FP) (H 2 O 2 /Fe 2+ ), photo-Fenton process (PhFP) (UV/H 2 O 2 / Fe 2+ ), and photocatalytic process (PhCP) (TiO 2 /UV). To perform this study, design of experiments methodology was applied. A full factorial design was
