摘要：
Interfacial tensions at concentrations of Sb(III) ranging from 2 . 10(-6) to 5 . 10(-4) mol 1(-1) in 0.1 M HCl and 2.9 M HClO4 mixture on the Hg-electrode were measured using the drop-time technique with long drop-times and a controlled convection of the solution. The dependence of the surface excess on concentration was determined. The adsorption was found to obey Langmuir isotherm. From the calculated surface area of antimony of 20 nm2 it was concluded, that complexes of antimony with chloride are the adsorbing species.
