Özet:

 In this study, kiwi fruit peels were functionalized using hydrochloric acid HCl, sulfuric acid H2SO4 and phosphoric acid H3PO4. The properties of the functionalized materials were determined. Fourier transform infrared spectrometer FTIR used to show functional groups caused by the agents. Crystalline or amorphous structure clarified by X-ray diffraction XRD analysis. Scanning electron microscope SEM revealed the changes by acidic agents on the surface of kiwi peel. The elemental composition was examined using energy-dispersive X-ray spectroscopy EDX analysis. The performance of kiwi peels functionalized with different acidic agents in sorption experiments were investigated. Kiwi peel functionalized with hydrochloric acid HAFKP, kiwi peel functionalized with sulphuric acid SAFKP, and kiwi peel functionalized with phosphoric acid PAFKP exhibited 94.53, 98.62, and 96.76 sorption, respectively, from 50 mL of 10 mgL dye solution for 0.1 g after 24 h. The data obtained for the sorption of the materials were evaluated with kinetic models. Pseudo-first order, pseudo-second order, Elovich and Bangham models considered the processes as time-dependent. The processes carried out with HAFKP and PAFKP were fit the pseudo-second order kinetic model and determined to interact strongly with dye via chemical bonds. SAFKP, on the other hand, interacts physically with dye according to the pseudo-first order kinetic model.

 Bu çalışmada kivi kabukları hidroklorik asit HCl, sülfürik asit H2SO4 ve fosforik asit H3PO4 kullanılarak fonksiyonelleştirildi. Fonksiyonelleştirilmiş malzemelerin özellikleri belirlendi. Ajanların neden olduğu fonksiyonel grupları göstermek için Fourier dönüşümlü kızılötesi spektrometresi FTIR kullanıldı. X-ışını kırınımı XRD analiziyle kristal veya amorf yapı açıklandı. Taramalı elektron mikroskobu SEM, kivi kabuğunun yüzeyinde asidik ajanların neden olduğu değişiklikleri ortaya koydu. Elementel bileşim, enerji dağılımlı X-ışını spektroskopisi EDX analizi kullanılarak incelendi. Farklı asidik ajanlarla fonksiyonelleştirilen kivi kabuklarının sorpsiyon deneylerindeki performansı araştırıldı. Hidroklorik asit ile fonksiyonelleştirilmiş kivi kabuğu HAFKP, sülfürik asit ile fonksiyonelleştirilmiş kivi kabuğu SAFKP ve fosforik asit ile fonksiyonelleştirilmiş kivi kabuğu PAFKP 0.1 g için 24 saat sonra 50 mLlik 10 mgL boya çözeltisinden sırasıyla  94.53, 98.62 ve 96.76 sorpsiyon sergiledi. Malzemelerin sorpsiyonu için elde edilen veriler kinetik modellerle değerlendirildi. Yalancı birinci derece, yalancı ikinci derece, Elovich ve Bangham modelleri prosesleri zamana bağlı olarak ele aldı. HAFKP ve PAFKP ile gerçekleştirilen proseslerin yalancı ikinci derece kinetik modele uyduğu ve boya ile kimyasal bağlar yoluyla kuvvetli etkileşime girdikleri belirlendi. SAFKP ise yalancı birinci dereceden kinetik modele göre boya ile fiziksel olarak etkileşime girdi.
