Abstract

The corrosion behavior of aluminum in 1M HCl solution in the absence and presence of expired Ranitidine drug was investigated using weight loss and electrochemical techniques. It was found that, the inhibition efficiency of Ranitidine depends on the concentrations. The inhibitive action of this compound discussed in terms of blocking the electrode surface by adsorption of the molecules through the active centers contained in its structure. The adsorption process follows Langmuir adsorption isotherm and El-Awady isotherm. The polarization curves indicate that this compound may act as mixed-type inhibitor. The variation of the open circuit potential of the aluminum electrode as a function of the period of exposure was measured and indicate that the addition of the inhibitor molecules, shift the corrosion potential (Ecorr) to less noble direction. The effect of temperature on the rate of corrosion was also, studied. Activated thermodynamic parameters were computed.
