3.4. Thermal analysis data studies
The thermal analysis data and thermogravimetric analysis
(DTA/TG) curves of the prepared sample are shown in Fig. 7. From
Fig. 7, partial loss of adsorbed water at 75.54 C and all adsorbed
water is lost at 108.85 C. The total weight loss is about 6% (very
small) at room temperature to 800 C due to there is no organic
decomposition in the heating process.
