“…Because of the general aggressiveness of acid solutions, organic inhibitors are commonly used to reduce the corrosion attack on metallic materials [1]. Among the inhibitors which are effective in acid solutions there are nitrogen containing compounds such as derivatives of amines [2][3][4] pyridazine [5], quinoline and pyridine [6], pyrazole [7,8], pyrazine [9], acridine [10], benzimidazole [11][12][13] and triazole [14][15][16][17][18][19]. Previous studies have shown that indole and some its derivatives display good inhibiting effects on steel and copper corrosion in acid solutions [20][21][22][23][24][25][26][27][28].…”

Inhibitive action of gramine towards corrosion of mild steel in deaerated 1.0M hydrochloric acid solutions

et al. 2012

a b s t r a c tThe effect of addition of gramine on mild steel dissolution in deaerated 1.0 M hydrochloric acid was studied through potentiodynamic polarisation curves, electrochemical impedance spectroscopy and gravimetric measurements in the temperature range from 25°C to 55°C. Gramine was found to shift the corrosion potentials towards less noble values and decrease both dissolution of mild steel and hydrogen evolution reaction. Gramine did not affect the corrosion reaction mechanism (blocking effect). Results obtained from the several measurement techniques were in good agreement and revealed good inhibition efficiencies in the concentration range (0.75 mM Ä 7.5 mM) particularly at higher concentrations.

“…Aqueous extract of Rosemary leaves [7], Zenthoxylum -alatum [8] and Lawsonia [9] have been used to inhibit corrosion of metals. Corrosion inhibition of iron in hydrochloric acid solutions by naturally occurring Henna has been investigated [10]. An aqueous extract of plant material rhizome (Curcuma Longa L) powder has been used as a corrosion inhibitor for carbon steel [11].…”

The inhibition efficiency (IE) of an aqueous extract of beet root (BR) in controlling corrosion of carbon steel in well water in the absence and presence of Zn 2+ has been evaluated by mass loss method. The formulation consisting of 4 mL of BR extract and 50 ppm Zn 2+ offers 98% inhibition efficiency to carbon steel immersed in well water. A synergistic effect exists between BR extract and Zn 2+ . Addition of N-Cetyl-N,N,Ntrimethylammonium bromide (CTAB) does not change the excellent inhibition efficiency of the BR -Zn 2+ system. The BR -Zn 2+ system shows excellent IE up to 7 days. 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 Fe 2+ -betanin complex and Zn(OH) 2 . The film is found to be UV -fluorescent.

“…2 that both anodic metal dissolution of iron and cathodic hydrogen and oxygen evolution reactions were inhibited after the addition of Schiff base to the aggressive solution. This result is indicative of the adsorption of inhibitor molecules on the active sites of carbon steel surface [24]. The inhibition of both anodic and cathodic reactions is more pronounced with the increasing inhibitor concentration.…”

Investigation of Thermodynamic Parameters for Steel Corrosion in Acidic Solution in the Presence of N,N′-Bis(phloroacetophenone)-1,2 propanediamine

N,N 0 -Bis(phloroacetophenone)-1,2-propanediamine as corrosion inhibitor for steel in hydrochloric acid has been studied using electrochemical techniques and surface techniques. Results showed that the inhibition occurs through adsorption of the inhibitor molecules on the metal surface. The inhibition efficiency was found to increase with increasing inhibitor concentration and decreased with increasing temperature. Thermodynamic parameters for adsorption and activation processes were determined. Polarization data indicated that this compound acts as the mixed-type inhibitor and the adsorption basically obeys the Langmuir adsorption isotherm. The quantum chemical calculations were performed at the density functional theory level using B3LYP functional with the 6-31G (d,p).
