| Abstract: | A approach of preparation of monolithic silica column was reported, in which tetramethoxysilane and poly ethylene glycol were used as the material. An improved sol-gel process was adopted. The monolithic silica column has continuous gel skeletons and through-pores together with open mesopores. It has the advantage to separate samples with high-efficiency and high-speed. The effects of pH value and temperature of water-bath on the process of gelation were investigated and the mechanism of morphology was also discussed. |
