Journal ArticleDOI
Kinetics of photocatalytic oxidation of organic solutes over titanium dioxide
TL;DR: In this paper, the photooxidation rate of 22 organic solutes over a UV illuminated film of Degussa P25 titanium dioxide was studied over a 100-fold concentration range for each solute, generally from about 1 to 100 mg liter−1.
Journal ArticleDOI
Photo-oxidation of organic material in aqueous suspensions of titanium dioxide
TL;DR: In this article, the authors used uv-illuminated titanium dioxide powder in aqueous suspension for the disinfection of water, and compared the effect of solar illumination with a 100 W medium pressure mercury lamp, an 025 m2 parabolic trough solar collector and a flat bed.
Journal ArticleDOI
Formation of nitrate and ammonium ions in titanium dioxide mediated photocatalytic degradation of organic compounds containing nitrogen atoms
TL;DR: In this article, the photocatalytic oxidation of a related series of primary, secondary, and tertiary amines and other nitrogen- and sulfur-containing organic compounds over a UV-illuminated film of TiO{sub 2} has been studied.
Journal ArticleDOI
Purification of water with near-U.V. illuminated suspensions of titanium dioxide
TL;DR: In this paper, the authors used the Langmuir-Hinshelwood (L-H) kinetics for each solute to predict the mineralization rate at any solute concentration in aerated, aqueous suspensions of TiO 2 with near uv light.
Journal ArticleDOI
Photooxidative degradation of coloured organics in water using supported catalysts. TiO2 on sand
TL;DR: In this paper, the photocatalytic oxidation of methylene blue, Rhodamine B, methyl orange and salicylic acid have been studied in the presence of immobilized titanium dioxide coated sand in a flat bed configuration illuminated with a 100 W medium pressure mercury lamp and sunlight.
