The inhibition effect of [Cu+ 2 cation+ 3, 5-dimethyl pyrazole] mixture of different molar ratios
on the corrosion of carbon steel in a 0.5 M H2SO4 solution was studied using both weight
loss and galvanostatic polarization techniques. The inhibiting solutions were analyzed using
UV–visible spectrophotometric before and after polarization measurements. The results
revealed a complex formation between the two components, which was much more effective
than the inhibiting action of each additive separately. The inhibition mechanism was ...
