摘要：
The data on the structural features of the plant and mineral silica studied by infrared spectroscopy, electron spin resonance and nuclear magnetic resonance 1H porometry methods are compared with analytical and the X-ray phase analysis data. It was shown that the structural features depend on the precursor raw material and on the silica extraction technique. However, the structure of silica obtained from plants principally is not different from that of silica of mineral origin. The pore size on plant silica is smaller than that on mineral silica.
