Abstract: The inhibiting effect of 2-chloronicotinic acid on the dissolution of aluminium in various concentrations of HCl has been studied using weight loss and polarization measurements. The inhibition efficiency was found to increase with increasing concentration of the inhibitor. The effect of temperature on corrosion inhibition was investigated. The results indicate the decreased inhibition efficiency for the increase in temperature. The inhibitor was found to be adsorbed on aluminium surface probably following Langmuir adsorption isotherm at higher concentrations of HCl.
