Evaluation of the combined solar TiO2/photo-Fenton process using multivariate analysis
(2004-04-21)
The effect of combining the photocatalytic processes using TiO 2 and the photo-Fenton reaction with Fe3+ or ferrioxalate as a source of Fe2+ was investigated in the degradation of 4-chlorophenol (4CP) and dichloroacetic ...

Photochemical transformation of antibiotics by excitation of Fe(III)-complexes in aqueous medium
(Elsevier B.V., 2014-01-30)
The degradation of sulfadiazine (STZ) and sulfathiazole (SDZ) induced by the excitation of ferric ions (Fe3+) was studied in this work. The effect of Fe3+ ion concentration, pH, iron complexation and irradiation source on ...
Iron availability in the presence of β-carotene in different mixtures
(Sociedade Brasileira de Ciência e Tecnologia de Alimentos, 2011)
Iron availability in the diet is very important because iron deficiency affects a large population in the world. The matrix where iron is present has an influence in its availability. The presence of β-carotene is a ...
From tin oxalate to (Fe, Co, Nb)-doped SnO(2): Sintering behavior, microstructural and electrical features
(Pergamon-Elsevier B.V. Ltd, 2008-12-01)
Highly reactive SnO(2)-doped nanocrystalline powders with average particle size of 20 nm and specific surface areas above 30 m(2)/g were obtained through the polymeric precursor method with tin oxalate (SnC(2)O(4)) as a ...
