    • A method of treating silica gel to improve its characteristics as a filter material. The method comprises the steps of preparing surface modified silica gel by introducing fluidizing gas into a reactor at least partially filled with silica gel particles so as to form a fluidized bed of the silica gel particles; and introducing a liquid reagent into the reactor so as to modify the surface of the silica gel particles by covalently bonding at least one functional group thereto. The liquid reagent may be prepared such that the functional group includes a 3-aminopropylsilyl group, a N-[2-aminoethyl]-3-aminopropylsilyl group, a N-[N-(2-aminoethyl)-2-aminoethyl]-3-aminopropylsilyl group or a mixture thereof. The liquid reagent can be an aqueous or non-aqueous solution containing 3-aminopropyltriethoxysilane, 3-aminopropyltrimethoxysilane, N-[3-(trimethoxysilyl)propyl]-ethylenediamine and/or N′-[3-(trimethoxysilyl)propyl]-diethylenetriamine.
    • 一种处理硅胶以提高其作为过滤材料的特性的方法。 该方法包括以下步骤:通过将流化气体引入至少部分填充有硅胶颗粒的反应器中以形成硅胶颗粒的流化床来制备表面改性硅胶; 并将液体试剂引入反应器中,以通过共价键合至少一个官能团来改变硅胶颗粒的表面。 可以制备液体试剂,使得官能团包括3-氨基丙基甲硅烷基,N- [2-氨基乙基] -3-氨基丙基甲硅烷基,N- [N-(2-氨基乙基)-2-氨基乙基] -3 - 氨基丙基甲硅烷基或其混合物。 液体试剂可以是含有3-氨基丙基三乙氧基硅烷,3-氨基丙基三甲氧基硅烷,N- [3-(三甲氧基甲硅烷基)丙基] - 乙二胺和/或N' - [3-(三甲氧基甲硅烷基)丙基] - 二亚乙基三胺的水溶液或非水溶液。
