In present study, 4-vinyl pyridine grafted Poly(ethylene terephthalate) (4-VP-g-PET) fibers were oxidized and used for adsorption of acid violet 7 (AV7) dye. For this purpose, 4-VP-g-PET fibers were N-oxidized and these oxidized fibers were investigated for dye adsorption under different experimental conditions. The pH of the medium, the initial concentration of the dye and time were the parameters for the AV 7 adsorptions. In addition, desorption and reusability of adsorbed PET fibers were also investigated. As a consequence of current study, the obtained findings were indicated below. N-oxide-4-VP-g-PET fibers were adsorbed significantly more dye than 4-VP-g-PET fibers. N-oxide-4-VP-g-PET fibers maximum adsorption of AV7 was observed at 22 mg g-1 polymer (pH 5). Approximately full of the adsorbed AV 7 dye was desorbed (60%) from inoculated PET fibers. Ten removal-desorption cycles indicated that the reactive fibers were favourable for use it again without notable change in removal capacity.

Bu çalışmada, 4-vinil piridin (4-VP) aşılanmış Poli(etilen tereftalat) (PET) lifler oksitlenerek asit viyolet 7 (AV7) boyasının adsorpsiyonu için kullanılmıştır. Bu amaçla 4-VP aşılanmış PET lifler N-oksitlenme yapılarak boya adsorpsiyonu farklı deneysel koşullarda araştırılmıştır. AV7 adsropsiyonuna ortam pH'sı, boyanın başlangıç derişimi ve sürenin etkileri incelenmiştir. Ayrıca boya adsorpsiyonu yapılmış PET liflerin desorpsiyonu ve tekrar kullanılabilirliği de incelenmiştir. Bu çalışma sonucunda aşağıdaki bulgular elde edilmiştir. 4-VP aşılanmış PET liflerin oksitlenenleri, 4-VP aşılanmış PET liflere göre önemli miktarda daha fazla boya adsorplamıştır. N-oksit-4-VP-g-PET lifinin maksimum adsorpsiyon kapasitesi 22 mg g-1 olarak gözlenmiştir. N-oksit-4-VP-g-PET lif üzerine adsorpsiyon için optimum pH 5 bulunmuştur. Adsorplanan AV7 boyasının tamamına yakını (%60) aşılanmış PET liflerden desorbe edilmiştir. Ard arda 10 kez tekrarlanan adsorpsiyon-desorpsiyon işlemi ile aşılanmış PET liflerin adsorpsiyon kapasitesinde önemli bir azalma olmadan tekrar kullanılabilirliği gözlenmiştir.
