Adsorption of thiamine (vitamin Bi), riboflavin (B₂), and pyridoxine (B₆) from aqueous solution onto amorphous silica surface was studied. The investigation of adsorption of tocopherol (vitamin E) and its short-chained analogues from hexane and aqueous micellar solution was performed. Some data on mechanism of vitamin adsorption and structure of adsorption layer were obtained by electron spectroscopy and mass-spectrometry.
