Candesartan: A pharmaceutical product as effective corrosion inhibitor for aluminum in acidic solution

Blog Article

The corrosion performance of aluminum in 1 M hydrochloric acid solution in the existence and absence of Candesartan drug was examined utilizing, potentiodynamic polarization (PDP) and AC impedance (EIS) tests.It was found that the inhibition efficacy (%IE) of Candesartan drug was influenced by its doses and click here temperature and reached to 92.9% at 40x10-6 M, 30oC.The adsorption isotherm agreed with Langmuir model.

From Tafel data the investigated Candesartan drug acts as mixed kind inhibitor.The influence of temperature on the rate of dissolution read more and the thermodynamic parameters in the existence and absence of Candesartan drug were also, studied and explained.All tests gave similar results.
