Abstract

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 experimentaldata 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 adsorptioncapacity of CFA was found to be 294.00 mg/g. The study showed that, CFA seems to be an effectiveand low cost adsorbent material when compared with commercial adsorbents for the removal of heavymetals from aqueous solutions.

Özet

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