Abstract

In this work, removal of phenol from aqueous solutions by strongly basic anion exchange resin (Relite 2 AS) has been investigated. The effect of resin dosage and solution pH on phenol removal was observed. Obtained results showed that the resin form has an important effect on phenol removal. In OH form, pH has slight influence on phenol removal but when the resins were converted to Cl form and solution pH was increased to 11, percent removal of phenol increased. Removal of phenol was 97% in Cl form and 57 % in OH form of resin. The Freundlich model describes the phenol removal onto the two different forms. On the other hand, pseudo-second order kinetic fit well with experimental results. Kinetic of resin in Cl form is faster than in OH form. The 97% of phenol removed from solution in Cl form in 60 minutes. When the OH form was used, 50% of phenol removed from solution.

Özet

Bu çalışmada, kuvvetli bazik anyon değiştirici reçine (Relite 2AS) ile sulu çözeltilerden fenol giderilmesi incelenmiştir. Fenol giderilmesine; reçine miktarı ve çözelti pH`ının etkisi saptanmıştır. Elde edilen sonuçlar, iyon değiştirici reçine formunun fenol giderilmesinde önemli bir etkiye sahip olduğunu göstermiştir. Hidroksit formundaki reçine ile yapılan çalışmalarda fenol giderilmesine çözelti pH`sinin önemli bir etkisi yok iken, klörür formundaki reçine kullanıldığında ve çözelti pH`si 11` e ayarlandığında fenol giderim yüzdesinin arttığı saptanmıştır. Hidroksit formundaki reçine kullanıldığında fenol giderilmesinin % 57; klorür formundaki reçine kullanıldığında ise % 90 civarında olduğu görülmüştür. Denge çalışmalarında elde edilen sonuçlar Freundlich izoterm modeline uygunluk göstermiştir. Kinetik çalışmalarda elde edilen sonuçlar yalancı ikinci mertebe kinetik modeline uygunluk göstermiştir. Klorür formundaki reçinenin fenol giderim kinetiğinin hidroksit formundaki reçinenin kinetiğinden daha hazlı olduğu saptanmıştır. Klorür formundaki reçine ile 60 dakikada fenolün % 97`si giderilmişken, hidroksit formundaki reçine de 60 dakika da % 50 si giderilmiştir.
