| dc.description.abstract | Fe is one of the heavy metals that are harmful if levels exceed the thres hold. This material is often found in waste output streams, both industrial waste and house hold waste. The presence of iron in the water is a thing to watch out for and be considered because of its toxic if it enters in to the human body. To reduce the concentration of these metals Fe, an alternative that can be used is by adsorption process using zeolite 4A synthesized from fly ash of oil palm. The method used in the Fe metal adsorption process is a batch method. This study begins with the equilibrium curve to determine the optimum contact time. Analysis of adsorption results performed by AAS. The parameters used in this study is the initial concentration of 100 ppm, the stirring speed of 150 rpm, a dose of 1 gram of zeolite 4A, the variation in pH of the solution (4, 5, 6, 7 and 8) and temperature (30, 40, 50, 60 and 70°C). Results showed that the time to achieve the equilibrium state for 4 hours, with the highest percentage of adsorbed Fe is 98.0% of 100 ppm metal Fe(II) is used, the optimum operating conditionsare at pH 6 and room temperature (≈ 30oC). | en_US |
