Basic Blue 41 boyar maddesinin inaktif sucul bitki Myriophyllum spicatum tarafından biosopsiyonunun yalancı izotermlere uygulanması

Boyar maddelerin sulu ortamda ayrılmasında biosorpsiyon işleminin yaygın kullanıldığı ve araştırmaların sürdürüldüğü bilinmektedir. Bu çalışmada inaktif sucul bitki Myriophyllum spicatum’un sucul ortamdaki Basic Blue 41 (BB41) boyar maddesini biyosorpsiyonunun yalancı izotermlere uygunluğu araştırılmıştır. BB41 boyar maddesinin inaktif bitki tarafından adsorpsiyon hızının yalancı ikinci dereceden hız modeline uyduğu belirlenmiştir. Yalancı ikinci dereceden hız denkleminden ve katsayılarından yola çıkarak hesaplanan yalancı izotermler ile gerçek izotermler karılaştırıldığında inaktif bitki için en uygun izotermin gerçek izotermler olduğu bulunmuştur.

Application of pseudo izoterms on the biosorption of Basic Blue 41 by submerged aquatic plant (Myriophyllum spicatum)

Biosorption is a well known process to remove dyes from aqueous media, and investigation have been deeply sustained for the efficient process. In this study, the application of pseudo isotherms on the biosorption of Basic Blue 41 (BB41) dye by non-living submerged aquatic plant Myriophyllum spicatum has been investigated. Kinetics of the adsorption process was found to be best defined by the pseudo second order adsorption kinetic model. The pseudo isotherms of adsorption process were also studied with the help of pseudo second order constants and it was found that the real isotherms described the non-living submerged plant/BB41 process better than the pseudo isotherms.
