Immobilisation of TiO(2) for combined photocatalytic-biological azo dye degradation.
(2010) In Water Science and Technology 62(3). p.525-531- Abstract
- The biodegradability of the azo dye Remazol Red RR (100 mg/l) was evaluated using unadapted activated sludge and the experiment confirmed the recalcitrance of the dye. Using a combination of photocatalysis and an aerobic biological step, the biodegradability was improved significantly and complete removal of both colour and COD were achieved. Furthermore, TiO(2) was successfully immobilised on borosilicate glass slides by calcination, which facilitates reuse of the catalyst. The catalytic activity of the immobilised TiO(2) was close to that of suspended TiO(2). A reduced activity was however observed when the TiO(2) slides were used repeatedly. When comparing NaOH, calcination and UV irradiation for regeneration of the TiO(2) slides,... (More)
