Surface complexation modelling was used to provide a quantitative description of the adsorption of some B vitamins (thiamin, pyridoxine and pyridoxamine) onto a fumed silica surface as a function of pH, ionic strength and sorbate concentration. Equilibrium parameters were determined using the basic Stern model and the GRFIT program package.
