Abstract

Two calixarene-functionalized biopolymers (calixarene-functionalized chitosan and calixarene-functionalized cellulose) have been synthesized and duly characterized using FTIR, TGA and elemental analysis techniques. Furthermore, their anion extraction behaviors at various pH values have been evaluated toward dichromate and arsenate anions. Results indicated that calixarene-functionalized chitosan against dichromate ion exhibited higher extraction capability than calixarene-functionalized cellulose. Intriguingly, although a less extraction efficiency against dichromate anion was obtained by calixarene-functionalized cellulose, the arsenate anion extraction results showed that calixarene-functionalized cellulose is more effective ionophore than calixarene-functionalized chitosan.

Özet

İki kaliksarene-fonksiyonlu biyopolimerler (kaliksaren-fonksiyonlu kitosan ve kaliksaren-fonksiyonlu selüloz) sentezlenmiş ve FTIR, TGA ve element analiz gibi teknikler kullanılarak uygun bir şekilde karakterize edilmişlerdir. Ayrıca, çeşitli pH lardaki anyon ekstraksiyon davranışları dikromat ve arsenat anyonlarına karşı incelenmiştir. Sonuçlar dikromat iyonuna karşı kaliksaren-fonksiyonlu kitosanın kaliksaren-fonksiyonlu selüloza göre daha büyük ekstraksiyon kabiliyetinin olduğunu gösterdi. İlginç bir şekilde, dikromat anyonuna karşı daha düşük bir ekstraksiyon verimliliği kaliksaren-fonksiyonlu selüloz ile elde edilmesine rağmen, arsenat anyon ektraksiyon sonuçları kaliksaren-fonksiyonlu selülozun kaliksaren-fonksiyonlu kitosana göre daha etkin iyonofor olduğunu gösterdi.
