Amorphous silica gel as a surfactant for saponins: support, synthesis, and texture characteristics

Silica sorbent samples were synthesized at different temperatures using saponins as surfactants in an acidic medium. The textural properties of the sorbent samples were studied by adsorbing benzene vapor onto them. The specific surface area of the sorbents at different temperatures was found to be 854,2 m2/g, while the pore volume ranged from 0,32 to 0,90 cm3/g. The average diameter of the pores was found to be in the range of 0,8-32,1 nm.
