Abstract: Inhibition of aluminum corrosion in NaOH solution by anionic surfactant as sodium (lauryl) sulphate, cationic surfactant as cetyl trimethyl ammonium bromide and non-ionic surfactant as Triton-X 100 has been studied using weight-loss and hydrogen evolution methods. It is found that the inhibition efficiency depends on the type of SAS as well as its concentration. The order of increasing inhibition is as follows ...Thermodynamic parameters are calculated.
