Abstract

The synthesis of poly(acrylonitrile-co-acrylamide) (p(AN-co-AAm)) hydrogels with different amounts of acrylonitrile (AN) and acrylamide (AAm) monomers were carried out by concurrent use of redox and microemulsion polymerization techniques. The prepared hydrogels were amidoximated for sorption of uranyl ion from aqueous medium. Batch type $UO_2^{2+}$ ion sorption by p(AN-co-AAm) (0.25:1 mole ratio) was carried out and an sorption capacity of 220 mg $UO_2^{2+}$ mg/g dried hydrogel was found. The highest amount of UO22+ ion sorption, 277 mg/g dry gel was accomplished at pH 4.

Özet

Değişik miktarlarda akrilonitril (AN) ve akrilamit (AAm) monomerleri içeren poli(akrilonitril-ko-akrilamit) ((p(AN-co-AAm)) hidrojelleri eş zamanlı redoks ve microemülsiyon polymerizasyon teknikleri kullanılarak gerçekleştirilmiştir. Hazırlanan hidrojeller sulu ortamdan uranil iyonları soğurumu için amidoxime reaksiyonuna tabii tutulmuşlardır. P(AN-co-AAm) (0.25:1 mole oranında) tarafından batch tipi $UO_2^{2+}$ iyonu çalışmaları yapılmış ve kuru hidrojel başınan 220 mg/g soğurma kapasitesi bulunmuştur. En fazla uranil iyonu soğurma kapasitesi pH 4 de gram kuru jel başına 277 mg/g olarak gerçekleştirilmiştir.
