Abstract
Telah dilakukan sintesis dan karakterisasi membran ZSM-5 dengan penyangga kasa jenis 304 ukuran 200 dan 400 mesh dan jenis kasa AISI 316 ukuran 180 mesh. Tujuan penelitian ini adalah mensintesis membran ZSM-5 dengan penyangga kasa jenis 304 ukuran 200 dan 400 mesh dan jenis kasa AISI 316 ukuran 180 mesh dan mengkarakterisasi membran ZSM-5 hasil sintesis. Sintesis membran dilakukan dengan cara melapiskan prekursor ZSM-5 ( coating) pada penyangga kasa yang telah diberi perlakuan dan dipanaskan pada suhu 90 °C selama 4 hari. Selanjutnya, membran yang dihasilkan dikarakterisasi engan metoda X-ray diffraction (XRD), scanning electron microscope-energy dispersive spectroscopy (SEM-EDS) dan Fourier-transform infrared (FTIR). Hasil citra SEM-EDS menunjukkan bahwa ukuran membran ZSM-5 yang semakin besar, menghasilkan jumlah lubang atau pori semakin banyak dengan luasan pori yang semakin kecil. Pola difraksi XRD menunjukkan bahwa membran yang dihasilkan mempunyai intensitas tertinggi pada 2 8o dan 23o yang merupakan karakteristik dari ZSM-5. Hasil spektra FTIR menunjukkan adanya serapan pada bilangan gelombang 450 cm - 1 yang merupakan ciri khas membran ZSM-5. Characterization of ZSM-5 Membranes Synthesized by Variation of Support Types and Sizes. Synthesis and characterization of ZSM-5 membrane were carried out with 304 type 200 and 400 mesh gauze supports and 180 mesh AISI 316 gauze types. The purpose of this study was to synthesize ZSM-5 membrane with 304 type 200 and 400 mesh gauze support and AISI 316 type 180 mesh size 180 mesh and characterize the synthesized ZSM-5 membrane. Membrane synthesis was carried out by coating the pre-treated gauze support with the ZSM-5 precursor and was heated at 90 °C for 4 days. Furthermore, the resulting membrane was characterized by X-ray diffraction (XRD), scanning electron microscope-energy dispersive spectroscopy (SEM-EDS) dan Fourier-transform infrared (FTIR). The SEM-EDX analysis shows that the increasing of ZSM-5 membrane size allowed pores number to increase with smaller pore surface area. The X-ray Diffraction pattern (XRD) shows that the resulting membrane has the highest intensity at 2 of 8o and 23o as the characteristics of ZSM-5. The FTIR spectra results show absorption at wavenumbers 450 cm -1 which is a characteristic of ZSM-5 membranes.
