Evaluation of Corrosion inhibition properties of pharmaceutically active compound Cefotaxime sodium on mild steel surface in sulfuric acid medium

Cefotaxime sodium is applied in various concentrations in 0.5M sulphuric acid towards the mild steel and analyzed through weight loss, potentiodynamic polarization and EIS studies at 298 to 338oK. It gives good inhibition activity at lower temperature. Activation parameters, Gibbs free energy, Entha...
