Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh waktu leaching kaolin terhadap sintesis zeolit NaP. Padatan hasil leaching kaolin dikarakterisasi dengan XRF (X-ray Flourosence) dan padatan hasil sintesis dikarakterisasi dengan spektroskopi inframerah (FTIR), difraksi sinar-X (XRD), dan Scanning Electron Microscopy–Energy Dispersive X-ray (SEM-EDX). Hasil karakterisasi XRF menunjukan bahwa rasio Si/Al pada waktu leaching 4,8, dan 12 jam mengalami peningkatan dari 1,53 menjadi 2,82; 3,18; dan 3,68. Hasil karakterisasi XRD dan FTIR menunjukan bahwa zeolit NaP terbentuk pada waktu leaching dan hidrotermal masing-masing 4 dan 72 jam. Fase sodalit terbentuk pada waktu leaching dan hidrotermal masing-masing 4 dan 12-48 jam. Sedangkan pada sintesis zeolit NaP dengan variasi leaching 8 dan 12 jam masih terdapat fase lain yaitu zeolit NaY. ================================================================= The purpose of this research is to study the effect of kaolin leaching time on the synthesis of zeolite NaP. Solid products of leached kaolin were characterized with XRF (X-ray Flourosence) and solid products of synthesized were characterized with infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The result of XRF characterization indicate that ratio of Si/Al for kaolin leached time 4, 8, and 12 hours increased from 1,53 to 2,82; 3,18; dan 3,68. The result of XRD and FTIR characterization show that the zeolite NaP formed with 4 hours kaolin leached and hydrothermal time of 72 hours. Phase impurities sodalite formed in 12-48 hours. There was some impurity on the synthesized for 8 and 12 hours kaolin leached like zeolite NaY.
