Photochemical decomposition of a fluorotelomer unsaturated carboxylic acid, C 3 F 7 CFCHCOOH (1), in the presence of WO 3 and an electron acceptor (S2O82- or H 2 O 2 ) in water under visible-light irradiation was investigated. Under an O 2 atmosphere, 1 was not decomposed either by TiO 2 (P25) or WO 3 alone. A combination of WO 3...
The photochemical decomposition of perfluoroether carboxylic acid C 2 F 5 OC 2 F 4 OCF 2 COOH (EEA), which is being introduced in industry as a surfactant alternative to environmentally persistent and bioaccumulative perfluorocarboxylic acids, was investigated by use of water-soluble tungstic heteropolyacids H 3 PW 12 O 40 and H 4...
