dc.description.abstractFly ash is the result of burning coal in steam generator furnace which is fine and pozolanic and fly ash is produced in high volume every year. The main components of coal fly ash are silicate (SiO2), alumina (Al2O3), and iron oxide (Fe2O3). In this study, fly ash was used as an adsorbent which was activated by chemical activation methods using NaOH activator with variation of the activator concentration (0, 1, 3 and 5) M and physical (burning at 600 oC). The results of this study indicate that the optimum condition of fly ash activator concentration is in 3 M NaOH activator, obtained a moisture content was 0.35 %, surface area was 46,2791 m2/g and SiO2 content was 60,87 %. Fly ash with the optimum conditions obtained has a maximum adsorption efficiency of Fe 10 ppm solution was 86,43%. The effectiveness of fly ash in absorbing Fe ions at various adsorbate concentrations, it was found that the higher adsorbate concentration would get the greater absorption efficiency by the adsorbent. The adsorption mechanism of Fe ion in this study follows the Freundlih adsorption isotherm model.en_US
