In this study, coal fly ash (CFA) was evaluated as a low cost adsorbent for the removal of nickel(II) ions from aqueous solution. Experimental parameters affecting the adsorption process such as pH, adsorbent dosage, contact time and initial metal ion concentration were optimized. The experimental data were modeled by Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm models. Langmuir model resulted in the best fit of the adsorption data. The maximum monolayer adsorption capacity of CFA was found to be 294.00 mg/g. The study showed that, CFA seems to be an effective and low cost adsorbent material when compared with commercial adsorbents for the removal of heavy metals from aqueous solutions

NİKEL GİDERİMİ İŞLEMLERİNDE KÖMÜR UÇUCU KÜLÜNÜN DÜŞÜK MALİYETLİ ADSORBAN MALZEMESİ OLARAK KULLANIMI

Öz

Bu çalışmada, kömür uçucu külü sulu çözeltilerden nikel(II) iyonlarının gideriminde düşük maliyetli adsorban olarak değerlendirilmiştir. pH, adsorban miktarı, temas süresi ve başlangıç ağır metal derişimi gibi adsorpsiyon işlemini etkileyen deneysel parametrelerin optimizasyonu gerçekleştirilmiştir. Elde edilen deneysel veriler Langmuir, Freundlich ve Dubinin-Radushkevich (D-R) izotermleri kullanılarak modellenmiştir. Langmuir modelinin adsorpsiyon verilerine daha iyi uyduğu belirlenmiştir. Uçucu külün en yüksek tek tabaka adsorpsiyon kapasitesi 294,00 mg/g olarak bulunmuştur. Yapılan çalışma, ticari adsorbanlarla karşılaştırıldığında uçucu külün sulu çözeltilerden ağır metallerin gideriminde etkin ve ekonomik bir adsorban malzemesi olabileceğini göstermiştir
