Photocatalytic degradation of a textile azo dye, Sirius Gelb GC on TiO 2 or Ag-TiO 2 particles in the absence and presence of UV irradiation: The effects of some inorganic anions on the photocatalysis
(2004)
The aqueous phase photocatalytic degradation of Sirius Gelb GC used in the textile industry, was investigated. In order to optimize the working pH, three different dye solutions were prepared at pH 3.5; 7.0 and 11.0. One ...
Determination of ultra trace arsenic species in water samples by hydride generation atomic absorption spectrometry after cloud point extraction
(2011)
Cloud point extraction (CPE) methodology has successfully been employed for the preconcentration of ultra-trace arsenic species in aqueous samples prior to hydride generation atomic absorption spectrometry (HGAAS). As(III) ...
Surfactant enhanced-spectrophotometric determination of uranium (VI) at trace levels by using eriochrome black T as a chelating agent
(2011)
A sensitive and relatively selective spectrophotometric method is proposed for the rapid determination of uranium using Eriochrome Black T (EBT) being a 2, 2'-dihydroxy azo benzene derivative metal indicator in the presence ...
