Abstract

Abstract A homologous series of new gemini cationic surfactants were synthesized and characterized using micro elemental analysis, FTIR, 1 H-NMR and mass spectra. The surface activities of these amphiphiles were determined based on the data of surface tension. Critical micelle concentration, effectiveness of the surface tension reduction, efficiency of adsorption, maximum surface excess, minimum surface area and critical ...
