PHOTODEGRADATION OF DYES RB-5 AND RL-6 USING Fe2O3-TiO2 SEMICONDUCTORS
In the present work, the photodegradation of Reactive Black Number 5 (RB-5) and Lanasol Red No 6 (RL-6) dyes was studied using modified TiO2 semiconductors with 5, 10 and 20 wt% Fe2O3. The materials used were synthesized by the sonochemical method; To determine their physicochemical properties, the techniques of XRD, Scanning Electron Microscopy (SEM), RD-UV-Vis spectrophotometry and FTIR were used. Photoactivity studies were carried out in a batch reactor equipped with a cooling jacket, magnetic stirring, and UV or Vis lamps. The depth of degradation was monitored by UV-vis and total organic carbon analysis.
