dc.description.abstract50 ppm sodium salt of 1-hydroxyethane-1,1-diphosphonic acid (HEDP) offered only 11% inhibition efficiency (IE) to corrosion of mild steel immersed in neutral aqueous environment containing 60 ppm chloride. When 50 ppm Zn2+ is added to 50 ppm HEDP, the IE increased to 98%. The influence of Zn2+  on the corrosion -inhibition by HEDP is discussed based on the results obtained from UV-visible, FTIR and luminescence spectra. Presence of Zn2+ facilitates. the transport of HEDP from the bulk of the solution to the metal surface; both the anodic reaction and cathodic reaction are controlled effectively.en_US
