Fumed silica was used for adsorption of Triton X‐100 from electrolyte solutions. Influence of such parameters as the kind of fumed silica and its pretreatment, pH, ionic strength and ionic composition of solution on the process of surfactant adsorption has been studied using differential capacity measurements at a controlled growth mercury drop electrode. The kinetics of Triton adsorption on silica have also been studied. It was found that under optimal conditions 0.1% of fumed silica removes completely 5 ppm of Triton X‐100 in time shorter than 1 minute.
