摘要：

Corrosion inhibition in the presence of Streptomycin in 1M HCl was studied using the weight loss technique at 303 to 338 K. The results obtained revealed that the inhibition efficiency decreased with increase in temperature. Inhibition occurred through adsorption of the Streptomycin molecules on the metal surface. The apparent activation energies, enthalpies and entropies of the dissolution process and the free energies and enthalpies for the adsorption process were determined and discussed. The fundamental thermodynamic functions were used to evaluate important inhibitive properties of Streptomycin.
