| Abstract: | Synthesis of zeolite P by hydrothermal method using rice husk ash as silicon source was optimized.It was found that the maximum calcium exchange ability of zeolite P is 305.4 mg/g when synthesis was carried out at 1.2 of n(Na2O)/n(SiO2) molar ratio,7.0 of n(SiO2)/n(Al2O3) molar ratio,25 of n(H2O)/n(Na2O) and 85℃ of crystallizing temperature for 10 h.analysis by X ray diffraction and SEM suggested the better characteristic peak and the narrower grain-size distribution. |
