Photodegradation of polycyclic aromatic hydrocarbon pyrene by iron oxide in solid phase

Sono-oxidation of soils: degradation of naphthalene by sono-Fenton-like process

“…Iron oxides, such as goethite (α-FeOOH), hematite (α-Fe 2 O 3 ), lepidocrodite (γ-FeOOH), and maghemite (γ-Fe 2 O 3 ), are natural minerals that are found in abundance everywhere in the environment and can be efficiently utilized as natural catalysts to oxidize a great variety of organic contaminants (Lu 2000;Tyre et al 1991;Wang et al 2009). Surface reactions to yield OH• radicals without the dissolution of iron-containing mineral in the presence of ultrasound irradiation may be expressed (Tyre et al 1991):…”

Photocatalytic Activity of Co:TiO2 Nanocomposites and their Application in Photodegradation of Acetic Acid

“…The removal of several aliphatic carboxylic acids 9,10 as well as aromatic acids such as benzoic acid, polycarboxylic acids, salicylic acid, chlorobenzoic acids, etc., [11][12][13][14] from water using TiO 2 catalyzed PCD has been reported. Besides this, the photocatalytic degradation of the higher aliphatic carboxylic acids such as branched C4 and C5 aliphatic acids using titanium dioxide has also been studied 15 .…”

Photocatalytic degradation of polycyclic aromatic hydrocarbon benzo[a]pyrene by iron oxides and identification of degradation products

“…Iron oxides are efficient, cheap and easily acquirable alternatives for the other existing photocatalysts. Wang et al (2009) investigated the photodegradation of mutagen pyrene utilising solid phase of iron oxides and detected pyreno as an intermediate compound. Benzo [a]pyrene is a potent carcinogen and considered an environmental indicator for PAH contamination (Cerniglia, 1992).…”
