Astrazon Red FBL Çözeltisinin Gama Işınlarıyla Renk Giderimi ve Detoksifikasyonu

Abstract

Bu çalışmada, Astrazon Red FBL boyasının sulu çözeltilerinin yüksek enerji ile etkileşimi sonrası renk giderimi ve detoksifikasyonu farklı deneysel koşullar altında (hava, doygun O2, 2.6 mM H2O2) araştırılmıştır. Bu kapsamda renk giderme, mineralizasyon, detoksifikasyon, pH, KOİ ve BOİ5 parametreleri takip edilmiştir. Biyobozunurluk (5 günlük biyolojik oksijen ihtiyacı/kimyasal oksijen ihtiyacı -BOD5/COD-) oranı, tüm çözeltiler için 2 kGy ışınlamada artmıştır. Astrazon Red FBL çözeltilerinin mineralizasyonunu ve renk giderimini sağlamak üzere hava için 5 kGy ve pH 9, doygun O2 için 5 kGy ve pH 11, 2.6 mM H2O2 için 7 kGy ve pH 11, optimum ışınlama koşulları olarak bulunmuştur. Yüksek enerjili ışınlarla muamele edilen Astrazon FBL çözeltilerinin toksisitesini ölçmek için microtox bioassay testi gerçekleştirilmiştir. Hava, doygun O2 ve H2O2 çözeltileri için sırasıyla %81.2, %86.7 ve %56.3 oranlarında 5, 5 ve 7 kGy'de toksisite azalması sağlanmıştır. Çalışmanın sonucu olarak, Astrazon Red FBL tekstil boyasının ışınlama teknolojisi ile arıtımının gerçekleştirilebileceği tespit edilmiştir.

Decoloration and Detoxification of Astrazon Red FBL Solution Using Gamma Rays

Abstract

In this study, decoloration and detoxification of Astrazon Red FBL dye solutions using gamma rays have been examined at different environments (air, O2 saturated, 2.6 mM H2O2). In this context, the decoloration, mineralization, detoxification, pH, COD and BOD5 parameters were followed. Biodegradability ( 5 days of biological oxygen demand/ chemical oxygen demand -BOD5/COD-) ratio has been improved up on 2 kGy irradiation for all solutions. Optimum irradiation conditions were found to be 5 kGy pH 9 for air, 5 kGy pH 11 for O2 saturated, 7 kGy pH 11 for 2.6 mM H2O2 to provide mineralization and decoloration of Astrazon Red FBL solutions. Microtox bioluminescent test was conducted to measure the toxicity of Astrazon FBL solutions treated with high energetic rays. Toxicity reduction has been achieved at 5, 5 and 7 kGy in the range of 81.2, 86.7 and 56.3 % for air, O2 saturated and H2O2 solutions, respectively. As a result of study, it is found that Astrazon Red FBL dye could be treated by irradiation technology.
