摘要：
The inhibitive synergistic effect between a cationic gemini surfactant, 1,2-ethane-bis(dimethyl dodecylammonium bromide) (designed as 12-2-12), and anionic surfactant, sodium dodecyl sulfonate (SDS) for the corrosion inhibition of A3 carbon steel in 1 mol L-1 HCl was investigated by weight loss. The inhibition system composed by 12-2-12 and SDS is efficient. The adsorption mechanism of the 12-2-12 and SDS on steel in acidic medium is discussed on the basis of experimental data and an adsorption model is proposed. Adsorption of inhibitor system on the A3 carbon steel surface in acidic medium obeys Langmuir's adsorption isotherm.
