Abstract

In
this study, the anionic hydrogels were prepared in existence of crosslinker (N,
N’-methylenebisacrylamide) by free radical addition reaction in aqueous
solutions of neutral acrylamide and 2-hydoxyethyl methacrylate monomers and anionic comonomers such as mesaconic acid with 2 carboxyl groups or aconitic acid with
3 carboxyl groups.

Hydrogels
were characterized by FT-IR and DSC analysis. The effects of temperature, pH,
adsorbent mass and concentration on uranyl ion adsorption onto the anionic
hydrogels were investigated.

It
was determined that adsorption of UO22+ ions to prepared
hydrogels did not change with temperature and increased with increasing pH.

The
adsorption of uranyl ion from
aqueous solutions onto the anionic hydrogels was evaluated by applying
Giles, Langmuir and Temkin isotherms to experimental results.

According
to the Giles adsorption isotherms classification of hydrogels UO22+ ions adsorption prepared from adsorption isotherms
formed, L type was determined and Langmuir parameters were calculated.











It
was determined that adsorption of UO22+ ions to hydrogels
prepared from RL values calculated for 1000 mg L-1UO22+ ion concentration is favorable.

hidrojellere UO22+ iyonu adsorpsiyonunun Giles
adsorpsiyon izotermleri sınıflamasına göre L tipi olduğu belirlenmiş ve
Langmuir parametreleri hesaplanmıştır.











1000 mg L-1 UO22+
iyonu derişimi için hesaplanan RL değerlerinden hazırlanan
hidrojellere UO22+ iyonlarının adsorpsiyonunun elverişli
olduğu belirlenmiştir.
