3.  Expired Zosyn Drug as Corrosion Inhibitor for Carbon Steal in Sodium Chloride Solution

Authors: M. Dan, N. Vaszilcsin, M. Labosel and B. Pancan


Abstract:

In this paper, the possibility to use expired zosyn as corrosion inhibitor for carbon steel in sodium chloride aqueous solution was investigated. The inhibitory effect has been studied by several methods : weight loss measurements, linear polarization, Tafel plots method for the kinetic parameters determination, scanning electron microscopy, all of them providing complete information about the inhibition mechanism. Furthermore, the inhibitory efficiency has been studied as a function of temperature.


Keywords: zosyn, expired drugs, corrosion inhibitor, inhibitory efficiency
