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.

The effect of ion exchange resin form on the removal of phenol from water

Öz

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.
