| titleOfInvention | Method for producing granular meso-porous silica |
| abstract | The present invention relates to a process for producing granular mesoporous silica, and more particularly, to a process for producing granular mesoporous silica having a high adsorbing ability and a high permeability coefficient and thus being highly utilizable as an adsorbent for aquatic pollutants. The present invention relates to a process for producing granular mesoporous silica comprising the steps of: 2.4 to 4.4 parts by weight of a surfactant; 12 to 22 parts by weight of a silica precursor; 1.7 to 3.2 parts by weight of a functional group precursor; A first mixing step of mixing the parts by weight; A first reaction step of producing a powdery mesoporous silica in an aqueous solution state by stirring and reacting the mixture after completion of the first mixing step; A precipitation step in which the reactant in the first reaction step is left as it is to precipitate the reactant and remove a part of the supernatant; A second reaction step in which 0.9 to 1.7 parts by weight of Na-alginate is added to 1 part by weight of alkali to the reaction product in which the supernatant is removed in the precipitation step, and the mixture is reacted and stirred to form gel state mesoporous silica; A second mixing step of mixing the calcium chloride solution with the reactant of the second reaction step in a droplet state and stirring the calcium chloride solution after the second reaction step; And a filtration step of filtering the mixture of the second mixing step by a screening method. |
