Removal of Heavy Metals From Aqueus Solution Using Activated Carbon Embedded Cryogels

Aktif Karbon Gömülü Kriyojeller Kullanılarak Atık Sulardan Ağır Metal Uzaklaştırılması

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.
