Abstract
The synthesis of zeolite from fly ash has been investigated. The method used for the synthesis of zeolite in this research is the smelting method followed by a hydrothermal process. The zeolite synthesis was characterized using XRD and SEM. Based on the research results, it was found that fly ash can be synthesized into Na-P zeolite with morphology like coral, and cancrinite zeolite and sodalite with morphology like seaweed. The optimum condition for zeolite synthesis occurred at a hydrothermal process at 160°C for 24 hours with the formation of cancrinite zeolite. The synthesized zeolite resulting from the separation of 4 M of HCl formed Na-P zeolite and silica phase crystals which had the most optimum absorption of ammonium with an adsorption capacity of 18.025 mg/g with the adsorption kinetics model in the form of pseudo-second-order with a constant rate of 0.557 h-1 .
