摘要：
The adsorption of purine and pyrimidine nucleobases from aqueous solutions on silica surface modified by preliminary adsorption of proflavine has been studied as depending on pH and adsorbate concentration. It has been shown that the bases interact with proflavine, the molecules of which are attached to neutral silanol groups of silica via hydrogen bonds. The equilibrium constants of the complexation reactions between the bases and adsorbed proflavine have been calculated.
