Synthesis of Mg/Al Hydrotalcite by Using Low Supersaturated Precipitation Method with Variation of Mole Ratio
This research aims to synthesize Mg/Al hydrotalcite with mole ratio variations of Mg/AlÂ precursor through low supersaturated precipitation method. Mg/Al hydrotalcite was synthesized withÂ Mg/Al mole ratio variation of 1:1, 2:1, 3:1, and 4:1. Mg/Al hydrotalcite was synthesized using NaOHÂ and Na2CO3 base solutions. The mixture of precursor was stirred for 2 hours then treated byÂ hydrothermal at 100 Â°C for 4 hours. Results of the synthesis Mg/Al hydrotalcite with mole ratioÂ variations is a white powder. The formation of the structure of Mg/Al hydrotalcite showed by certainÂ peaks in the FTIR spectra and XRD diffractogram.
The results of data analysisshowed that variation of mole ratio Mg/Alcauses a shift of peak inÂ the XRD diffractogram shifted towards the left along with a comparative increase in mole ratio Mg/Al,Â but the main functional groups on the compound Mg/Al hydrotalcite increasingly formed with better.
