Abstract

Ozone, a stong oxidative agent, not only removes the color of the effluent but also reduces the organic pollution values. Numerous decolorisation studies on reactive dyeing effluents by ozonation has been made considering low fixation degrees of reactive dyes. Hydrolysis of reactive dyes had been reported in some studies in order to simulate actual reactive dyeing effluents. However, the hydrolysis of reactive dyes primarily effects the bonding capacity and its effects on decolorisation needs to be discussed. Also different hydrolysis procedures had been reported in some studies while no hydrolysis had been reported in some others. At this study, effects of various hydrolysis procedures using different temperatures, process time and alkalis on decolorisation and COD reduction of CI Reactive Yellow 167 has been investigated. Results indicate neglicible effect of hydrolysis on decolorisation

Özet

Ozon kuvvetli bir oksidandır ve tekstil atık sularının ozonlanması ile hem atık suyun rengi giderilmekte hem de organik kirlilik miktarı azaltılmaktadır. Fiske olmadan banyoda kalan oranının fazla olması nedeniyle reaktif boyarmaddeler ozonlama yoluyla renk giderimi çalışmalarında sıklıkla kullanılmışlardır. Literatürdeki çalışmalarda, numune reaktif boyarmadde çözeltileri gerçek boyama atık sularına benzetilmek için ozonlama öncesinde hidroliz edilmiştir. Reaktif boyarmaddelerin hidrolizi aslında bağ yapabilme kabiliyetleriyle ilgilidir. Bunun yanında; farklı araştırmacıların farklı hidroliz şartları uygulamaları hatta bir kısmının hidroliz yapmaması boyarmadde hidrolizinin ozonlama ile renk giderimi üzerine etkisi konusunda kafa karıştırıcıdır. Ozonlama ile renk giderimi çalışmalarında, gerçek boyama banyolarındaki boyarmaddenin hidroliz olma davranışını simüle etmek için deney çözeltilerine uygulanan boyarmadde hidroliz işlemininin gerekliliği üzerine literatürde yorum eksikliği görülmektedir. Bu çalışmada, CI Reactive Yellow 167 monoazo reaktif boyarmaddesinin ozonlama yoluyla renk gideriminde farklı sıcaklıklarda ve sürelerde, farklı alkaliler ile yapılan hidroliz işlemlerinin renk giderimine, ozon verimine ve KOİ giderimine etkisi karşılaştırılmalı olarak incelenmiştir. Deney sonuçları hidroliz işleminin renk giderimi üzerinde ihmal edilebilir derecede küçük etkiye sahip olduğunu göstermiştir
