Abstract
The equilibrium interfacial tension isotherms at the octane-water and toluene-water interfaces containing some model derivatives of hydropho bic sulfonamides from 2-(aminomethyl)pyridine and o-phenylenediamine a re determined and interpreted. The influence of the compound structure s and polarity upon the effectiveness and efficiency of adsorption are discussed. Compounds having a long hydrophobic alkyl chain are more s urface active than compounds having a substituted aromatic ring.
