Abstract

The adsorption of acridine from aqueous solutions onto fumed silica surface has been studied as a function of pH, ionic strength and sorbate concentration. The stability constants of acridine surface complexes with neutral and ionized silanol groups have been calculated with basic Stern model and GRFIT program software.
