Abstract
Corrosion of metals as age old as the origin of earth itself. In the past history, various means and methods have been employed to suppress corrosion. One of those methods to suppress corrosion is by using organic inhibitors. Since many of those organic inhibitors were found to be hazardous to the lives on earth. Hence it is the need of the time to go for eco-friendly corrosion inhibitors. Out of the various ecologically favorable inhibitors, amino acids are found to be the suitable corrosion inhibitors. In this study L-Valine has been chosen with Zn2+ ion to know its corrosion inhibition behavior on carbon steel in Cauvery water. Weight loss method has been employed for this investigation. The film formation has been authenticated by various electrochemical investigations such as FTIR, UV-Vis spectroscopy, Fluorometry, Potentiostatic polarization and Scanning electron microscopy. From the results of the above studies the probable mechanism for the corrosion inhibition has been proposed.
