Taguchi Deneysel Tasarım Yöntemi Kullanılarak Bromfenol Mavisi Biyosorpsiyonunun Modellenmesi ve Denge İzotermleri

Su ortamında boyaların varlığı, ekosistem kalitesini olumsuz etkilediği için küresel bir sorundur. Tehlikeli boyaların biyosorpsiyon yöntemiyle ayrılması düşük maliyetli ve etkili bir yöntem olarak kullanılmaktadır. Bu çalışmada Fomes fomentarius (L.) Fr. ve Trametes versicolor (L.) Lloyd biyosorbent olarak kullanılarak sulu çözeltiden Bromfenol Mavisinin giderimi çalışılmıştır. Taguchi deney tasarımında L9 (33) ortogonal dizi (OD) kullanılarak başlangıç pH değeri (2, 7, 12) başlangıç boya konsantrasyonu (25, 50, 75 mg L-1) ve temas süresi gibi (30, 150, 270 dk) kontrol edilebilir 3 faktör ve her faktörün 3 farklı seviyesinin biyosorpsiyon sürecindeki istatistiksel ilişkileri araştırılmış ve sistemin optimizasyonu yapılmıştır. Deneysel çalışmalar sonucunda parametrelerin optimum değerleri F. fomentarius ile biyosorpsiyonda temas süresi 270 dk, başlangıç pH değeri 2 ve başlangıç boya konsantrasyonu 50 mg L-1, T. versicolor ile biyosorpsiyonda temas süresi 150 dk, başlangıç pH değeri 2 ve başlangıç boya konsantrasyonu 50 mg L-1 olarak belirlenmiştir. Belirlenen ptimum koşullardaki boya giderim verimleri F. fomentarius için %78.34, T. versicolor için %69.28 olarak bulunmuştur. Biyosorpsiyon izotermleri Langmuir ve Freundlich denklemleri kullanılarak modellenmiştir. F. fomentarius ile yapılan deneylerde en iyi model uyumu Freundlich izotermi ile T. versicolor ile yapılan deneylerde en iyi uyum Langmuir izotermi ile sağlanmıştır. Giderim performansları göz önünde bulundurulduğunda her iki biyosorbentin de boya endüstrisi atıksularının gideriminde düşük maliyetli ve etkili biyosorbentler olarak değerlendirilebilecekleri sonucuna varılmıştır.

Modeling of Bromphenol Blue Biosorption Using Taguchi Experimental Design Method and Equilibrium Isotherms

The presence of dyes in the aquatic environment is a global problem because of the negative consequences on the ecosystem quality. Adsorption process is used as a low cost and effective method for removing hazardous dyes. This study investigated removal of Bromophenol Blue from aqueous solutions by Fomes fomentarius and Trametes versicolor. The statistical relationships of the parameters in the biosorption process by considering three controllable factors including initial pH value (2, 7, 12), initial dye concentration (25, 50, 75 mg L-1) and contact time (30, 150, 270 minutes) were investigated at three different levels and the biosorption process was optimized using Taguchi orthogonal array (L9 OA) experimental design. As a result of experimental studies, the optimal dye removal conditions were determined as the contact time of 270 minutes, pH: 2 and initial Bromophenol Blue concentration of 50 mg L-1 for F. fomentarius. The optimal dye removal conditions were determined as the contact time of 150 minutes, pH: 2 and initial Bromophenol Blue concentration of 50 mg L-1 for T. versicolor. For F. fomentarius and T. versicolor, the removal efficiencies at optimum conditions were 78.34% and 69.28%, respectively. Biosorption isotherms were modeled using the Langmuir and Freundlich models. The biosorption of Bromephenol Blue on F. fomentarius and T. versicolor fitted better in the Freundlich and Langmuir models by non-linearized equations, respectively. Both biosorbents can be promising for dyes removal from aqueous environment.
