Removal of arsenic from water using natural materials (Kula ebonite, zeolite)

Many important diseases appear if the water which contains arsenic is drinking above limit values. The arsenic toxicity is watched over at three valance inorganic forms.In this study, it is determined conditions which effect the adsorbance performance for removing the arsenic with natural materials (Kula ebonite and zeolite) using directly after having some modifications from synthetic As(III) solutions. The adsorption process was carried out by using batch method. The arsenic concentration which remained without adsorption was determined by AAS at 193,7 nm inN20/acetylene flame. However, there isn?t observed any significant adsorption value at Kula ebonite. Also there isn?t any remarkable adsorption value by using zeolite which was used directly or mixed with Al2(SO4)3, Al2(SO4)3 + NaOH solutions. Otherwise, it is observed a remarkable adsorption value, if the zeolit was used by mixing FeCl3 + FeCl3 + NaOH solutions. The adsorption capacity was found out 1,99 and 3,43 mg As(III) / g adsorbent respectively, at pH: 10, 20 0C temperature and 6 hours contact time. It is determined that the adsorption which was treating on two materials, fitted to Langmuir isotherms.
