Normal 0 false false false IN X-NONE X-NONE MicrosoftInternetExplorer4 Normal 0 false false false IN X-NONE X-NONE MicrosoftInternetExplorer4 This research has investigated adsorption of Fe with using fly ash adsorbent . Phases of adsorption of Fe is activated with H 2 SO 4 after that the fly ash were characterized by using XRF , FTIR and SEM . Determination of optimum conditions on the adsorption of Fe with adsorbent mass variations , variations in contact time , pH variation and variation concentration and adsorption isotherm study . Resulth show that the adsorption of Fe in optimum condition occurs in adsorbent mass of 2.5 g , for 60 minutes contact time with pH 4 at a concentration of 20 ppm . The results also able to adsorp up to 94 % Fe . The adsorption of Fe with using fly ash adsorbent was more fitted to the Langmuir model than to Freundlich model <w:LsdException Locked="false" Priority=
