Photocatalytic Degradation of an Anionic Surfactant by Tio2 Nanoparticle under UV Radiation in Aqueous Solutions
In this paper the photocatalytic degradation of the anionic surfactant, linear alkylbenzene sulfonicacid (LABSA) was investigated using UV radiation in the presence of TiO2. Our findingsdemonstrate that various parameters exert their individual influence on the photocatalytic degradationof surfactant in wastewaters. The mentioned parameters have been categorized as follow: the initialpH of the ...
متن کاملDispersion Properties of Nano YSZ Particles in Aqueous Suspensions
In the present research, the aqueous suspensions of nano-sized YSZ particles were prepared using a common and available dispersant (Dolapix CE64) at different pH values and their stability were evaluated through the sedimentation height, viscosity measurement, and microstructural observation. Different amounts of dispersant were tested and the optimum percentage was examined by measuring the vi...

متن کاملGinzburg-Landau theory of aqueous surfactant solutions
A simple two order-paraIneter Ginzburg-Landau theory for binary mixtures of water and amphiphile is introduced. The amphiphile concentration is described by a scalar, the orientational degrees of freedom of the amphiphile by a vector order parameter. Phase diagrams are calculated by minimizing the free energy functional. Several ordered lyotropic phases of lamellar, hexagonal, inverse hexagonal...
متن کاملSpectroscopy of single-walled carbon nanotubes in aqueous surfactant dispersion
Optical studies of single-walled carbon nanotubes (SWNTs) dispersed in aqueous surfactant suspensions have made significant progress since the discovery of their bright band-gap fluorescence in the near-infrared region [1]. In this article we report the systematic investigation of the effect of chemical purification and oxidation on the spectroscopic properties of SWNTs. The SWNTs samples we pr...
