摘要	The inhibition behaviour of 2-undecyl-1ethylamino-1methylbenzyl quaternary imidazoline (2UMQI) and KI on mild steel in 1.0 M H2SO4 solutions was investigated at 25 degrees C using electrochemical methods. The results indicated that 2UMQI inhibited the corrosion of mild steel and the extent of inhibition increased with 2UMQI concentrations. The inhibition action in the presence of 2UMQI is due to physical adsorption of 2UMQI. A mixed-inhibition mechanism is proposed for the inhibitive effects of 2UMQI. Inhibition efficiency of 2UMQI was enhanced by the addition of iodide ions. In the presence of KI, the potentials of unpolarization, E-u was observed and increased with KI concentration.
