| dc.description.abstract | Iron is one of the heavy metals that are harmful if the measure exceeds the threshold. Degradation of water quality caused by the existence of which the iron content that already exists on the ground because of the layers of soil through which the water contains certain chemical elements, one of them is iron. The methods to reduce the concentration of dissolved metals, particularly heavy metals are growing rapidly at the moment is adsorption, because not only easy to do but also quite high effectiveness and cost required is quite low. The adsorbent used is zeolite 4A synthesized from a mixture of silica and alumina with a volume ratio of 60/40, stirring the reactants need 3 hours and heating the gel need 8 hours. This research aims to study the effect of stirring speed and temperature the adsorption of metal Fe with zeolite 4A using Response Surface Method approach-Central Composite Design and obtain optimum conditions for the absorption of Fe metal with zeolite 4A. stirring Rapid is done by variation of 300 to 600 rpm and the temperature variation of 30 to 60 c. Ion concentration of Fe (II) sulfate was analyzed using AAS. The results obtained showed that zeolite 4A able to adsorb up to 97.439% Fe and obtained optimum conditions for stirring Rapid 1230 rpm and a temperature of 87 c. | en_US |
