Photocatalytic degradation of Eriochrome black-T dye using ZnO nanoparticles

In this study, ZnO nanoparticles were synthesized by co-precipitation method. The particles were used for degradation of Eriochrome black-T dye by examination at three different pH values. It was observed that the adsorption of dye onto ZnO nanoparticles surface is strongly dependent on the pH of the solution which plays an important role in photocatalytic degradation. Decomposition of Eriochrome black-T dye at pH 11 occurred at higher rate than other pHs. (C) 2014 Elsevier B.V. All rights reserved.
