Abstract

In this study, degradation of Reactive Red 141 (RR141) present in textile dyeing waste water was investigated by catalytic wet hydrogen peroxide oxidation over iron-containing ZSM-5 zeolite catalysts prepared by ion-exchange and hydrothermal synthesis methods. Higher decolorization (18.3%) and degradation (17.6%) degrees were obtained by waste water of dyeing with 0.5 wt% over ion-exchanged FeZSM-5 catalyst than those with waste water of dyeings in high dye concentration. Color removal was increased with H2O2 amount (up to 5 mmol) added to the reaction mixture. Decolorization degree increased from 15.7% to 18.6% in the combination of CWPO and ultrasound for waste water of dyeing with 0.5 wt%. However, as the concentration of dye in the waste water increased, the positive effect of ultrasound on decolorization disappeared

Özet

Bu çalışmada, tekstil boyama suyundaki C.I. Reactive Red 141’in (RR141)’in iyon değişimi ve hidrotermal sentez metodu ile hazırlanmış demir içeren ZSM-5 zeolit katalizörleri üzerinde ıslak peroksit oksidasyonunu (CWPO) ile giderilmesi incelenmiştir. İyon değişimli FeZSM-5 katalizörü üzerinde, 0.5 kütle yüzdesindeki boyama atık suyu için, yüksek boya derişimli atık sulara göre daha yüksek renk giderimi, %18.3 , ve daha yüksek aromatik giderim, %17.6, sonuçları elde edilmiştir. Reaksiyon karışımına eklenen H2O2miktarı (5 mmol’e kadar) ile renk giderimi artmıştır. 0.5 kütle yüzdesindeki boyama atık suyu için ultrases katkılı CWPO ile renk giderimi %15.7’den %18.6’ya çıkmıştır. Bununla birlikte, atık sudaki boya derişimi arttıkça ultrasesin renk giderimi üzerindeki olumlu etkisi kaybolmuştur
