Paper Title:
The Effect of PH on the Efficiency of Isoniazid as Corrosion Inhibitors of Brass in 3.0% NaCl Solution
  Abstract

This paper investigates the Isoniazid as chemical corrosion inhibitors for brass in 3.0% NaCl solution of different pH, employing polarization curves, electrochemical impedance spectroscopy(EIS), weight loss, and SEM. It is found that the inhibition efficiency of Isoniazid enhances with the increasing of the solution pH, from about 71% at pH 6.5 to 92% at pH 10.5. This improvement is attributed to the stronger adsorption of Isoniazid in alkaline solution, to prevent the occuring of the corrosion reaction of brass.
