| Abstract | ||
| Degradation of hardly degradable textile dyes in wastewater using DBD plasma method becomesa competitive technology for primary decomposition. In the same trend, newcomplex Dielectric Barrier Discharge Plasma device was been used in this study to evaluate its results in degradation of textile dyes. The six dyes used are from different classes (acid, basic and reactive) and structure to cover all the bases of dye. Different parameters asexposure time, ozone and dye concentration and their effect on%efficiency (η) of color removal of dyes from their solution were investigated. The de-colorization kineticsandboth chemical oxygen demand (COD), the effect of final product of the degradation process on the aquatic live is expressed using biological oxygen demand (BOD) analysis. The resultantstudy show that, the maximum color removal was obtained by treating the dyesolution for 90 sec using ozone concentration 20g/m2 and concentration of dye 0.5g/l for all the dyes for all the dye. Kinetic studies were been also considered and the obtained results were following first-order reaction. | ||
