SINTESIS DAN KARAKTERISASI SILIKA GEL DARI ABU SEKAM PADI DENGAN MENGGUNAKAN NATRIUM HIDROKSIDA (NaOH)

Abstract: The synthesis and characterization of silica gel from rice hull ash by using NaOH has been done. The synthesis of silica gel from rice hull ash was done by incineration through a heating for 4 hours with the temperature variation at 700^oC, 800^oC, and 900^oC. The product (Rice hull ash) washed with H₂SO₄and then continued with Na₂EDTA. The silica gel can be synthesized from the rice hull ash by adding H2SO4 solution into the Sodium Silicate (Na₂SO₃) at temperature 500^oC for 30 minutes. The silica gel from the synthesis can be characterized using infrared spectroscopy and X-Ray diffraction. The result of this research showed the same pattern with the comparator silica gel (Kiesel gel 60).
