G. Gunasekaran et al., ENHANCED SYNERGISTIC INHIBITION BY CALCIUM GLUCONATE IN LOW CHLORIDE MEDIA .1. KINETICS OF CORROSION, Proceedings of the Indian Academy of Sciences. Chemical sciences, 108(4), 1996, pp. 399-405
2-Carboxy ethyl phosphonic acid (2-CEPA) in the presence of Zn2+ ions
synergistically inhibits mild steel corrosion in 60 ppm chloride solut
ions. Calcium gluconate (CG) enhances inhibition. Electrochemical and
weight change methods are used to study synergistic inhibition, and th
e mechanism of inhibition is discussed.
