Abstract
Abstract Eleven TiO2 powders as catalysts have been studied in process of safranin T degradation in aqueous medium using mechanochemical, microwave and ultrasonic techniques. The degree of degradation has been controlled by means of spectrophotometric analysis of safranin T solutions before and after treatment and total organic carbon measurements. XRD, DTA-TG and BET analysis, FTIR spectroscopy and mass spectrometry of initial and spent catalysts have been carried out for explanation of obtained results. It has been established that the catalytic activity of TiO2 under mechanochemical treatment depends on phase composition and dispersity (specific surface area). Particularly, catalytic activity of mono-phase titanias inversely depends on specific surface area of initial catalyst. Sono- and microwave catalytic degradation were less effective.
期刊介绍：
The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
