| Abstract | ||
| The present study is the first describe the synthesis of solid catalyst from Iris persica Leaves. Solid catalyst was hydrothermally synthesized after determining the ratio of silica from different parts of Iris persica. Leaves extract are the best silica sources that can be used in synthesizing solid catalysis, the flowers, bulbs and rhizomes do not content a significant amount of silica. The synthesized solid catalyst was characterized by Fourier Transform Infrared (FTIR) spectroscopy, X-ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM). The results obtained by X-ray diffraction (XRD) show moderate average crystal size of 36.30nm. The average pore size, pore volume and surface area were determined by Brunauer-Emmett and Teller (BET) method with values of 18.88nm, 0. 12mL.g-1 and 21.60 mL. g-1 respectively. Finally, Transmission Electron Microscopy (TEM) was used to find the average crystal size and shape of catalyst, showing 21.82 nm of its average crystal size. The results verified that solid catalyst get from the hydrothermal condition, present a good solid catalyst characteristic and then can be suitable for using in adsorption and ion exchange applications. | ||
