Abstract

The synthesis of sodalite from natural minerals from Gowa has been successfully carried out using the hydrothermal method. The natural mineral used as starting material was processed with the addition of NaOH. The synthesis results were then characterized using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The results of FTIR characterization showed a typical absorption peak at wave numbers 660-740 cm^-1, indicating the presence of sodalite structure. The XRD characterization results showed a diffraction pattern corresponding to the sodalite structure, with diffraction peaks at 2θ angles around 14°, 24°, and 32°. The results of this sodalite synthesis show that the hydrothermal method can be used to produce sodalite with a good structure from natural minerals as starting material.
