Summary, etc. A novel triazine based corrosion inhibitor, 6-benzyl-(2-chlorobenzyl) amino 3-thioxo-3, 4-dihydro-1, 2, 4-triazin- (2H)-5-one (BCATDT) has been synthesized and characterized using various spectroscopic techniques. Corrosion inhibition efficiency and other corrosion parameters of BCATDT have been calculated using weight loss measurements, potentiodynamic polarization studies and electrochemical impedance spectroscopy techniques at three different temperatures (303 K, 313 K and 323 K). Among the 0.5 M and 1M HCl solutions 99.55% efficiency is reported for 0.5M solution corresponding to 200 ppm BCATDT. As the acid concentration doubled, only &lt; 7% efficiency decreases even at 323K (92.32%). The potentiodynamic polarization indicates that BCATDT act as an efficient mixed type inhibitor and the most suitable isotherm is found to be the Langmuir adsorption isotherm. The experimental results are then shown to be in conformity with theoretical parameters under B3LYP/6-31G* of Gaussian 03 soft ware. Molecular simulation studies are also performed by Monte Carlo simulation for studying the adsorption of BCATDT on to the various unit cell of iron surface such as Fe (111) Fe (110) and Fe (100) etc.
