Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh variasi rasio mol Na2O/SiO2 terhadap pembentukan zeolit dari kaolin Bangka Belitung secara langsung. Variasi rasio mol Na2O/SiO2 yang digunakan sebesar 0,3; 0,4; 0,5; 0,7; 0,9; 1,1 dan 1,3. Sintesis zeolit dilakukan dengan kaolin sebagai prekursor melalui tahap pengadukan dan hidrotermal pada suhu 100°C selama 120 jam. Padatan hasil sintesis dikarakterisasi menggunakan difraksi sinar-X (XRD), spektroskopi inframerah (FTIR) dan Scanning Electron Microscopy Energy Dispersive X-Ray (SEM-EDX). Hasil karakterisasi dengan XRD dan spektroskopi inframerah menunjukkan fase zeolit Na-P terbentuk pada variasi rasio mol Na2O/SiO2 = 0,5; 0,7 dan 0,9. Pada variasi rasio mol Na2O/SiO2 = 0,3; 0,4; 0,7; 0,9; 1,1 dan 1,3 terbentuk fase sodalit, selain itu pada rasio mol Na2O/SiO2 = 0,3 juga terbentuk fase zeolit Na-A. Hasil SEM-EDX menunjukkan morfologi hasil sintesis pada variasi rasio mol Na2O/SiO2 = 0,5 dan 0,7 dengan bentuk beraneka ragam dan tidak beraturan dengan adanya agregat. Rasio mol SiO2/Al2O3 sampel rasio mol Na2O/SiO2 = 0,5 dan 0,7 berturut-turut sebesar 0,77 dan 0,78. ================================================================================================================================
The purpose of this research was studied the effect of variation Na2O/SiO2 mole ratio towards synthesis zeolite from kaolin Bangka Belitung through direct synthesis. Variation of Na2O/SiO2 mole ratio were used are 0,3; 0,4; 0,5; 0,7; 0,9; 1,1 and 1,3. Synthesis of zeolite was done with kaolin as precursor by stirring and hydrothermal process at 100°C for 120 hours. Solid products were characterized using infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The result of XRD difractometer and infrared spectroscopy showed zeolite Na-P was formed at Na2O/SiO2 mole ratio = 0,5; 0,7 and 0,9. On Na2O/SiO2 mole ratio = 0,3; 0,4; 0,7; 0,9; 1,1 and 1,3 sodalite were formed, furthermore on Na2O/SiO2 mole ratio = 0,3 also formed zeolite Na-A. The result of SEM-EDX showed that the morphology of samples on Na2O/SiO2 mole ratio = 0,5 and 0,7 are various shape and irregular shape with agregate. SiO2/Al2O3 mole ratio of sample on Na2O/SiO2 mole ratio = 0,5 and 0,7 are 0,77 and 0,78 respectively.
