The present invention relates to a microporous silica gel used to adsorb organic compounds such as oils comprising porous organic silica gel as an active ingredient, and hydrolyzes a silica precursor having four or more alkoxy groups in an aromatic or aliphatic body in the presence of a surfactant. And it provides a porous silica gel for adsorption of non-polar volatile organic substances having a pore size of less than 50nm and a surface area of 200 ~ 2000 m 2 / g prepared by dehydration, washing. According to the present invention, silica having good adsorption properties to non-polar organic materials and particularly adsorbing and removing oily organic materials dispersed in air or polymer or in water, and especially adsorbing and removing oily organic materials dispersed in polymer Gel material is provided.n n n n Porous, silica gel, adsorption, in air, underwater |
