SYNTHESIS OF THE ZEOLITE 4A AND ITS APPLICATION IN WATER TREATMENT

Abstract

This paper presents the simple method of synthesis zeolite 4A from rice husk ash. By using the current physical methods such as X - Ray diffraction (XRD), infrared spectroscopy (IR), this study identified the characterization of zeolite 4A. The  formula of  zeolite 4A is Na₂O.Al₂O₃.2SiO₂.2H₂O. To simulation of zeolite 4A in sample water, the experiment of this study indicated that the content of substances is decreasing in general. The content of nitro and iron decrease 1.8 and 6.3 times, respectively. Thus, zeolite 4A can be useful in water filter and water treatment.
