Abstract:
A carbonated hydrocalumite was synthesized by the microwave method for being used as antacid. The gel was formed using Ca and Al nitrate solutions in a basic medium (NaOH+Na2CO3), then, this gel was aged and heated in a domestic microwave for 2.5 min (1250 W). The obtained white solid was washed with distilled water, dried in an oven at 100 °C for 18 h and characterized by different techniques such as: X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), BET surface area measurements, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). Finally, the carbonated hydrocalumite was tested as antacid by using a synthetic gastric juice and its activity was compared with a commercial antacid formulated with hydrotalcite. Results showed that the carbonated hydrocalumite was more effective than that commercial antacid.
