Photodegradation of Reactive Black 5, Direct Red 28 and Direct Yellow 12 using UV, UV/HO and UV/HO/Fe: a comparative study

Kinetic modelling of TOC removal by H2O2/UV, photo-Fenton and heterogeneous photocatalysis processes to treat dye-containing wastewater

“…H 2 O 2 was used at 0.25, 0.5, 1, 2 g/L (Schrank et al 2007) and 5 g/L to study the behaviour with an excess of oxidant for the three processes (López-López et al 2013). Samples were collected from the photoreactor every 15 min (Bali et al 2004;Schrank et al 2007), and samples from the heterogeneous photocatalysis process were filtered through a 0.45-lm Millipore filter to remove particles of TiO 2 (Alaton et al 2002). The amount of catalysts used were 40 mg/L of Fe 2?…”

Comparison of treatment and energy efficiency of advanced oxidation processes for the distillery wastewater

“…Various dye solutions like Reactive Black 5, Direct Red 28 and Direct Yellow 12 for treatment using UV, UV/ H 2 O 2 and UV/H 2 O 2 /Fe 2? process and reported that photoFenton process increases the decolorization and mineralization within short irradiation time by Bali et al (2004). Few researches focused on distillery effluent treatment using AOP.…”

Degradation of Alizarin Yellow R using UV/H2O2 advanced oxidation process

“…For instance, azo dyes which are one of the most common synthetic dyes can be decomposed into carcinogenic amines [5]. The release of these dye contaminated wastewaters into the ecosystem creates a significant source of pollution, which also leads to eutrophication and perturbation of the aquatic life [6,7]. In addition, it is vital to treat these dye effluents compared to treating other colorless organic compounds because even the presence of small amounts is toxic [8].…”
