ABSTRACT:
The Inhibition Efficiency (IE) of Trisodium Citrate (TSC) in controlling corrosion of carbon steel in RO water in the absence and presence of Zn2+ has been evaluated by weight-loss method. The formulation consisting of 150ppm TSC and 10ppm Zn2+ has 72.5% IE. It is found that the inhibition efficiency of TSC increases with the addition of Zn2+ion. A synergistic effect exists between TSC & Zn2+. Polarization study and characterization surface analysis studies confirm the protection of the carbon steel surface by inhibitive film. A suitable mechanism for corrosion inhibition has been proposed based on the results obtained from the above studies.
