Abstract	Adsorption of sodium bis(2-ethylhexyl) sulfosuccinate (Aerosol OT) and silver and gold nanoparticles on SiO2 from heptane solutions has been investigated by spectophotometery and CHN analysis. The adsorption isotherm of Aerosol OT is described by the Langmuir equation. Sorption capacity (2.4 × 10–4 mol/g), sorption constant (9.0 m3/mol), and area per Aerosol OT molecule in an adsorption layer (0.83 nm2) have been determined. It has been shown that, at Aerosol OT concentrations lower than 6 × 10–4 M, gold and silver ((0.3–6) × 10–4 M) are simultaneously extracted by 98%; however, they have no effect on the adsorption and determination of the surfactant.
