Özet
Bu çalışmada, Fe3+ şelatlanmış Cibacron Blue F3GA immobilize poli(akrilamid-allil glisidil eter [p(AAm-AGE)- CB-Fe3+] kriyojelin boya (Congo Red, Reactive Green) uzaklaştırma için potansiyel kullanımı araştırılmıştır. Kriyojel, radikalik polimerizasyon ile sentezlenmiştir. Cibacron Blue, kriyojel üzerine kovalent olarak bağlanmış ve Fe3+ iyonları ile şelatlanmıştır. Maksimum adsorpsiyon kapasiteleri, Congo Red için 14.50 mg/g kriyojel; Reaktive Green için 18.78 mg/g kriyojel olarak belirlenmiştir. Ayrıca, hem Congo Red hem de Reactive Green için Freundlich izoterminin uygun olduğu belirlenmiştir. Bu çalışma, p(AAm-AGE)-CB-Fe3+ kriyojelik materyalin yüksek derişimdeki farklı boyalar için adsorban olarak etkin bir şekilde kullanılabileceğini göstermiştir.
In this study, the potential use of Fe3+ chelated Cibacron Blue F3GA immobilized poly(acrylamide-allyl glycidyl ether) [p(AAm-AGE)-CB-Fe3+] cryogel to remove dyes from aqueous solutions was evaluated. Cryogel was prepared by radical polymerization. Cibacron Blue F3GA was covalently immobilized on p(AAm-AGE) cryogel and then chelated with Fe3+ ions. Maximum adsorption capacities were determined as 14.50 mg/g cryogel for Congo Red and 18.78 mg/g cryogel for Reactive Green. It was also determined that Freundlich isotherm was convenient for both dyes. More than 90% of the adsorbed dyes were desorbed in all cases. This study indicates that p(AAm-AGE)-CB-Fe3+ cryogelic material can be efficiently used as adsorbent for different dyes at high concentrations.
