Chemistry, Physics and Technology of Surface| Резюме: | Safranin T degradation in aqueous solutions has been studied as effect of mechanochemical, ultrasonic, and microwave treatments in the presence of titanium dioxide catalysts with different characteristics. Liquid phase (safranin solution) has been analyzed before and after catalysis by spectrophotometry. Solid phase (TiO2 catalysts) has been examined by DTA-DTG and XRD analysis, IR spectroscopy, and mass-spectrometry. All the kinds of treatments have been found to result in dye destruction, mechanochemical one being the most effective. The activity of monophase TiO2 catalyst varies as reciprocal of their specific surface area whereas that of biphase TiO2 one varies inversely with on the structure of interface contact zone. |
