UTILIZATION OF COAL FLY ASH AS LOW-COST ADSORBENT MATERIAL FOR NICKEL REMOVAL APPLICATIONS
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 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.
