Title: Preparation method of spherical silica microparticles from Biomass and spherical silica microparticles made by thereof
Inventor: CHUN JIN YOUNG
IPC: C01B33/187
Filed: 2020-08-03
Abstract: The present invention relates to a method for preparing spherical silica particles from biomass, and spherical silica particles prepared thereby. The method for preparing spherical particles from biomass includes the steps of: a first step of reacting biomass with an aqueous alkali solution to prepare a silicate solution; a second step of mixing the silicate solution with polyethylene glycol (PEG) to prepare a first mixture; a third step of adding an acid to the first mixture and carrying out agitation to precipitate silica particles; and a fourth step of collecting the silica particles precipitated in the third step and washing the same with distilled water. Herein, the silicate solution in the first step may be extracted through filtration under reduced pressure, and the silica particles in the fourth step may be collected through filtration under reduced pressure or centrifugal separation. In addition, the method according to the present invention is characterized in that the processing temperature of the third step is controlled to control the size of the spherical silica particles. When the third step is carried out at a temperature lower than room temperature within a range of 1-100℃, micrometer-scaled silica can be prepared. When the third step is carried out at a temperature higher than room temperature, nanometer-scaled silica particles can be prepared. Since the method according to the present invention uses a low temperature and low concentration of aqueous alkali solution, there are advantages in terms of processing convenience and cost saving.
