Synthesis and characterization of zeolite derived from Buriram sugarcane bagasse ash and Narathiwat kaolinite
Keywords:Sugarcane bagasse ash, Narathiwat kaolinite, Zeolite, Cation exchange capacity
In this research studied the synthesis of zeolite from sugarcane bagasse ash and Narathiwat kaolinite. The first step, silica was synthesized from sugarcane bagasse ash. A comparative study of NaOH concentrations was varied at 2 M 2.50 M and 3 M, respectively for 3 h at 100 °C by refluxing method. The results showed that yield of silica 55% at optimum 2.50 M NaOH concentrations. Silica was characterized by Fourier transform infrared spectroscopy (FTIR) technique. The staring materials were silica from sugarcane bagasse ash and Narathiwat kaolinite in the ratio of 3 : 7 by the refluxing method under temperature 100 °C at various NaOH concentration and crystallization times. The results found that Na-P zeolite at 3 M NaOH concentration for 10 h. The zeolite indicated that result in the research and confirmed by XRD and FTIR. The cation exchange capacity (CEC) was 351 meq/100g.
