| Abstract: | TiO2 assisted photodegradation of malachite green (MG) has been examined in TiO2 dispersions under both UV and visible light and found that degradation is faster in UV-light (λ 320nm). Adsorption is prerequisite for the TiO2 assisted photodegradation and the extent of degradation have been discussed in terms of the Langmuir-Hinshelwood model. Like most semiconductors the photocatalytic nature of TiO2 is pH dependent because of its amphoteric nature. It has been found that pH ranging from 3-5 is suitable for the photodegradation of this system. |
