The analysis of characterization of zeolite modified from fly ash using iron oxide and manganese oxide

Abstract Fly ash is the residue from burning coal in form of fine and light particles can be harmful to environment life. Whereas fly contains high silica so that it used as a precursor for zeolite blinding. Zeolite an adsorbent aquatic waste needs improved absorb more adsorbate. Therefore, necessary modify ash, such coating with manganese iron oxide. The made extraction synthesize using hydrothermal method. In this study, was found about 45.20% synthetic successfully coated oxide evidenced by results FTIR XRD. This indicated presence at absorption 453.29 cm −1 on XRD aimed 2θ = 37.356°; 47.337°; 51,879°; 57.966°; 61.822° 67.5552°. Meanwhile, were band 447.50 diffraction peaks 30,643° 60,322°.
