Abstract

This paper describes the synthesis process of zeoJit NaX material from unburned rice husk ash, including the following steps: (i) Step 1: Create a NaSiOi solution by heating rice husk ash in sodium hydroxide solution to create the NaSiOi precursor; (ii) Step 2: Create a sodium aluminate solution by dissolving aluminum powder in sodium hydroxide solution; (iii) Step 3: Create an intermediate mixture by mixing the NaSiOi solution from step (i) with the NaSi aluminate solution from step (ii) in the reaction vessel; (iv) Step 4: Create an aluminosilicate gel by vigorously stirring the intermediate mixture obtained from step (ii) for 2 hours at 50°C; and (v) Step 5: Heat the aluminosilicate gel mixture from step (iv) to 90°C and maintain for 4 hours; The solid residue was filtered, centrifuged, and dried at 100°C until no change in weight was obtained to obtain NaX zeolite material in powder form.
