“…Several inhibitors have been used to prevent corrosion of carbon steel in aqueous solution. Inhibitors such as chromate [1,2], molybdate [3,4] pertechnitate [5], nitrate [6,7], phosphate [8,9], silicates [10], cations [11], organic inhibitors [12,13], carboxylates [14,15,16] and tannins [17,18], have been used as corrosion inhibitors. Much work has not been done using K 3 [Fe(CN) 6 ] as corrosion inhibitor.…”

The inhibition efficiency (IE) of K 3 [Fe(CN) 6 ] in controlling corrosion of carbon steel in aqueous solution containing 60 ppm of Clin the presence and absence of Zn 2+ has been evaluated by weight loss method. The formulation consisting of 100 ppm K 3 [Fe(CN) 6 ] and 50 ppm Zn 2+ offers 98% inhibition efficiency to carbon steel immersed in aqueous solution containing 60 ppm Cl -. A synergistic effect exists between K 3 [Fe(CN) 6 ] and Zn 2+ . As immersion period increases, the inhibition efficiency of K 3 [Fe(CN) 6 ]─ Zn 2+ system decreases. Polarization study reveals that this formulation controls the cathodic reaction predominantly. AC impedance spectra reveal that a protective film is formed on the metal surface. FTIR spectra reveal that the protective film consists of Prussian blue and Zn(OH) 2 . The film is found to be UV fluorescent.

“…Applications of this versatile inhibitor in various applications have been reported in the literature (Vukasovich, 1990). Similarly, the ability of gluconates to hinder corrosion of carbon steel, and their environmental compatibility, were considered by several others (Kadek and Lepin, 1970; Lahodny‐Sarc, 1995; Lahodny‐Sarc et al , 2000; Mor and Bonino, 1970; Mor and Wrubl, 1976; Pandey et al , 1987; Vanloyen and Zucher, 1990; Wrubl et al , 1985). In order to improve the action and to reduce the quantity of molybdate used to achieve good inhibition, especially in cooling water systems, other synergistic or complementary inhibitors were employed.…”

There is an increasing demand for eco‐friendly inhibitors for use in cooling water systems. Both calcium gluconates and molybdate are eco‐friendly, non‐toxic chemicals. The corrosion inhibition of calcium gluconate and sodium molybdate on carbon steel in neutral aqueous media was evaluated by means of weight loss, electrochemical polarisation and impedance techniques. A synergistic effect was observed when these two eco‐friendly non‐toxic inhibitors were used in protecting carbon steel. A non‐linear relationship existed between the concentrations of the two inhibitors showing a synergistic effect.

“…The efficiency and the mechanism of the corrosion inhibition by gluconates, either as single compound or in a mixture, have been described in a number of recent studies [2,[38][39][40][41][42][43][44][45]. A successful inhibition of carbon steel was obtained in the seawater or solutions containing different chloride concentrations by gluconate [1,2,40,[45][46][47][48][49].…”
