摘要: Abstract The chemical structures of three prepared amidoamine Gemini surfactant were confirmed using FTIR and 1HNMR spectroscopic methods. synthetic routes passed through two steps, the first one is formation amide second quaternization with dibromo propane. surface thermodynamic parameters determined from tension conductivity measurements. obtained critical micelle concentrations both techniques are similar. values CMC found to depend on solution temperature hydrophobic character. change in free energy micellization adsorption showed a tendency synthesized surfactants adsorb at interface then forming bulk. act as good antibiotic against some tested bacteria fungi.
