Can I read Size effects of nanocrystalline TiO2 on As(V) and As(III) adsorption and As(III) photooxidation on EtoBox?
Size effects of nanocrystalline TiO2 on As(V) and As(III) adsorption and As(III) photooxidation by Zhonghou Xu; Xiaoguang Meng is a Environmental Science article available to read on EtoBox.
What is Size effects of nanocrystalline TiO2 on As(V) and As(III) adsorption and As(III) photooxidation about?
The physicochemical properties of TiO 2 particles in the diameter range between 6.6 and 30.1 nm and the effect of the crystalline size on arsenic adsorption and photocatalytical oxidation were investigated. TiO 2 nanoparticles of different sizes were single-phase anatase. The adsorption capacity of the TiO 2 for As(III) and As(V) increased linearly with the N 2 Brunauer-Emmett-Teller surface area (S BET ) of the particles. There was not much difference in the rate of As(III) photooxidation when the diameter of the TiO 2 nanoparticles was between 6.6 and 14.8 nm. However, the As(III) photooxidation rate clearly decreased when the particle size increased to 30.1 nm. Arsenite photooxidation data could be fitted with a first-order kinetics equation.
