Kinetic studies of oxidative degradation of 1,4-dioxane present in aqueous solutions in the concentration range between 2.27 x 10(-3) mol/L (200 ppm) and 5.68 x 10(-3) mol/L (500 ppm) were conducted in batch rector. This analysis considers the hydroxyl radicals ((*)OH) produced by Fenton reagent as the main species responsible for the degradation process.(More)
Removal of Cr(3+) from aqueous solutions by electrocoagulation (EC) with multiple electrodes was studied with both bipolar and monopolar configurations. The influence of chloride ions, pH, initial Cr(3+) concentration and cell current on removal performance was investigated in a batch stirred cell. It was noted that, the enhancement of solubility of(More)
Six patients with hemoptysis were treated by endobronchial sealing, with n-butyl cyanoacrylate, of the bleeding segment or subsegment. There was an immediate arrest of bleeding without any recurrence for a mean follow-up period of 127 (+/- 67.17) days. Endobronchial sealing appears to be an effective method of managing hemoptysis.
The paper presents the study of electrocoagulation (EC) of aqueous dye solutions of two different industrial dyes in a batch stirred cell. Experiments were carried out with 200 mg/l individual concentration of methylene blue (MB) and eosin yellowish (EY) in presence of NaCl as electrolyte. Effect of operating time and current density on the decolorization(More)
Fenton’s oxidation process (using a mixture of hydrogen peroxide and ferrous ion) rapidly oxidizes these organic compounds under acidic conditions. Different molar ratios of H2O2 to the organic compound were used. This study describes oxidation of 4-chlorophenol and nitrobenzene, in aqueous solutions, as individual pollutant. A ratio of [H2O2] / [Fe] of 8.2(More)
