Nanocomposite material based on Iron nanoparticles colloidal (Fe?NPC) and Purine were used through this work. (Fe? NPC) was biosynthesized and characterized by dynamic light scattering (DLS) and UV-visible spectroscopy. Fe?NPC was evaluated as synergistic inhibition with two purine inhibitors namely 1H-pyrazolo[3,4-d]pyrimidin-4(2H)-one (PU1) and 6-[(1-methyl-4-nitro-5- imidazolyl) sulfanyl] purine (PU2) on the corrosion of carbon steel in 0.5 mol dm-3 H2SO4 solution by electrochemical techniques. The potentidynamic polarization curves indicated that PU1 and PU2 behave as a mixed-type inhibitor while in the presence of Fe?NPC and its mixture with PU1 and PU2 behave as a cathodic inhibitor. There is a synergism between purine inhibitors and the biosynthesis Fe? NPC, and the values of synergism parameter (S) are higher than unity.
