    • Abstract

       

      Epidesmine as a silicon source was used to synthesize NaP zeolite by a hydrothermal method. Parameters such as SiO$_2$/Al$_2$O$_3$ and H$_2$O/Na$_2$O molar ratios, reaction temperatures and reaction times were investigated for regulating the purity of the final product. The samples were characterized by X-ray diffraction, infrared spectroscopy and scanning electronmicroscope. The experimental results evidenced that a high-quality NaP zeolite was obtained at SiO$_2$/Al$_2$O$_3$ and H$_2$O/Na$_2$O molar ratios of 3.7 and 55, respectively, and at a temperature of 95$^{\circ}$C for 6.5 h of ageing. The BET surface area and total pore volume of the powders were 17.1359 m$^2$ g$^{−1}$ and 0.006845 cm$^3$ g$^{−1}$, and the pore size was $\sim$3.2 $\mu$m.
