Abstract

In this study poly hydroxyethyl methacrylate PHEMA based activated carbon AC embedded cryogel discs were synthesized, characterized and their application for nickel and copper removal from aqueous solutions were investigated. The effect of pH and initial metal concentration on the adsorption capacity of the cryogels were studied in batch systems. Desorption of heavy metal ions was also studied and it was shown that synthe- sized discs could be repeatedly used without significant loss in the adsorption capacity after five repetitive adsorption–desorption processes.

Aktif Karbon Gömülü Kriyojeller Kullanılarak Atık Sulardan Ağır Metal Uzaklaştırılması

Abstract

B u çalışmada poli hidroksi metakrilat temelli aktif karbon gömülü kriyojel diskler sentezlenmiş, karakterize edilmiş ve sulu çözeltilerden ağır metal giderimi incelenmiştir. Sentezlenen kompozit kriyojel disklerin adsorpsiyon kapasitesine pH ve başlangıç metal iyonu derişiminin etkisi kesikli adsorpsiyon süreci kullanılarak incelenmiştir. Metal iyonlarının desorpsiyon çalışmaları gerçekleştirilmiş ve ard arda yapılan beş adsorpsiyondesorpsiyon döngüsünden sonra kriyojellerin belirgin bir kapasite kaybına uğramadan tekrar kullanılabildiği gözlenmiştir
