Gemini surfactants that served as environmentally friendly corrosion inhibitors, have been successfully synthesized by the reaction of SDS/ CTAB with glucose/ EDTA as spacer. Their molecular structure is confirmed by 1H-NMR and FTIR spectroscopy. By tensiometric method, the surface activity of the synthesized Gemini surfactants has been determined in terms of various parameters like the critical micelle concentration, surface excess at the air/water interface, minimum area per surfactant molecule, surface pressure at CMC, changes of standard free energies of adsorption, micellization and transfer. The obtained Gemini surfactants having EDTA as a spacer, exhibit a considerably higher effectiveness against corrosion as compare to Gemini surfactants having glucose as spacer.

阳离子 (CTAB-EDTA-CTAB/CTAB-Glu-CTAB) 和阴离子 (SDS-EDTA-SDS/SDS-Glu-SDS) Gemini 表面活性剂的合成：表面和防腐性能

Gemini 表面活性剂作为环境友好型缓蚀剂，已通过 SDS/CTAB 与葡萄糖/EDTA 作为间隔物的反应成功合成。它们的分子结构由 1H-NMR 和 FTIR 光谱证实。通过张力测定法，合成的 Gemini 表面活性剂的表面活性已根据各种参数确定，如临界胶束浓度、空气/水界面的表面过量、每个表面活性剂分子的最小面积、CMC 的表面压力、标准自由的变化吸附能、胶束能和转移能。与具有葡萄糖作为间隔物的Gemini表面活性剂相比，获得的具有EDTA作为间隔物的Gemini表面活性剂表现出相当高的抗腐蚀效果。
