|Title:||Photocatalytic degradation of an azo dye, Acid Red 27, in aqueous solution using nano ZnO|
|Keywords:||Photocatalysis;Photodegradation;UV Light;Dyes;Zinc Oxide;Azo Dyes|
|Abstract:||Photocatalytic degradation of Acid Red 27 by nano ZnO has been investigated under different conditions. Optimum experimental conditions on catalyst amount, pH and dye concentration have been determined. Addition of some inorganic oxidizing species such as H2O2, K2S2O8 and KBrO3 up to a certain concentration increases the rate of degradation. The photodecolourisation and degradation kinetics are discussed in terms of Langmuir-Hinshelwood kinetic model.|
