Benzotriazole has been investigated to control the corrosion of 70/30 brass in 3.0 N nitric acid solution using weight
loss measurement and Scanning Electron Microscope (SEM) analysis. The measurements showed increase in inhibition
efficiency with increase in the concentration of the Inhibitor but decreases with the increase in temperature. Scanning Electron
Micrographs reveal the changes in the metal surface morphology in the presence of benzotriazole. Micrographs indicated that
the metal surface was in a better condition in the presence of the inhibitor than the specimen exposed in the absence of the
inhibitor
