Synthesis and Characteristics of Zeolite Y (Fajasitea) from Bagasse Ash <i>(Saccharum officinarum)</i> Using Hydrothermal Treatment in Pb^{2 +}Metal Adsorption

Abstract

The first stage to prepare bagasse ash to be synthesized. Furthermore, it will be in a furnace at a temperature of 600°C for 4 hours, then analyzed by SEM, BET, EDX, XRF to determine the morphology, surface area, elements and compounds contained in bagasse ash. The second stage is calcined using H2 gas stream, then TGA analysis. The third stage results from calcination, then hydrothermal with the addition of a molar variation of 10Na2O:xAl2O3 15SiO2: 300H2O namely mixing 3.06 grams of Al2O3, 3.168 grams of NaOH, 1.908 grams of silica from bagasse ash and 20.87 grams of H2O (pH=7). Then the sample will be analyzed using XRD and SEM. The next step will be to test zeolite Y which is synthesized into a metal solution medium, namely Pb2+ 25 ppm. The results of the XRF of bagasse ash contained a SiO2 content of 54% which can be used as a synthetic zeolite with a surface area of 291,761 m2/g, after being synthesized, the surface area of ​​zeolite Y is 648,178 m2/g and % adsorption 97.43% for Pb metal. While commercial zeolite has a surface area of ​​133.122 m2/g with adsorption % 98.84%.
