“…A close comparison between Tables 2 and 3 revealed that WL decreases with increasing temperature indicating that the CR decreases with increase in temperature. The value of IE was increased with rise in temperature suggesting physical adsorption mechanism [35]. These results indicate that the adsorption of investigated extract shield the metal surface at room temperature [36].…”

“…The addition of the Myrtus extract did not change the pH of the sulfamic acid solution. After different immersion time (30,60,90, 120 and 150 min) at temperature range (25,30,35 and 40°C) by immersion of MS into 100 ml acid solution with and without various doses of inhibitors, the specimen were taken out of the test solution, rinsed with bi-distilled water, dried as before, and weighed again accurately [23]. After the specified period of time, the specimen were taken out of the test solution, rinsed with bi-distilled water, dried as before, and weighed again accurately [25].…”

The effect of an aqueous extract of Myrtuis communis on the corrosion behavior of mild steel (MS) in 5% NH 2 SO 3 H solution has been investigated by the following techniques: weight loss (WL), potentiodynamic polarization (PP), electrochemical impedance spectroscopy (EIS), and electrochemical frequency modulation techniques (EFM). The inhibition efficiency (IE) increased with increase in inhibitor dose and increased with rise in temperature. The thermodynamic parameters of corrosion and adsorption processes were calculated and discussed. The adsorption of this extract was found to obey Langmuir adsorption isotherm. The PP tests indicated that the extract is mixed type. The results obtained from the three different techniques were in good agreement. The morphology of the surface was analyzed and discussed.

“…The inhibitor molecules can be adsorbed onto the metal surface through electron transfer from the adsorbed species to the vacant electron orbital of low energy in the metal to form a co-ordinate link. The inhibition efficiency depends on many factors 55) including the number of adsorption centers, mode of interactions with metal surface, molecular size and structure. It is well known that iron has co-ordination affinity toward nitrogen, sulfur and oxygen-bearing ligands.…”

:Inhibition performance of Lornoxicam & Tenoxicam against corrosion of carbon steel in 1 M H 2 SO 4 solutions was investigated by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements. The inhibition efficiency increased with increasing inhibitor's concentration, but decreased with increase in temperature. Potentiodynamic polarization curves showed that, the inhibitors were of mixed type. The apparent activation energy ( ) and other thermodynamic parameters for the corrosion process have also been calculated and discussed. The inhibition of carbon steel corrosion is due to the adsorption of the inhibitor molecules on the surface, which follows Temkin adsorption isotherm. The mechanism of inhibition was discussed in the light of the chemical structure of the undertaken inhibitors.

“…This indicates that terpolymer compounds are adsorbed on the metal surface rendering inhibition effect. The Tafel curves are quite parallel in nature indicating that the hydrogen evolution is activation controlled and the mechanism is not altered after addition of the inhibitor [16]. The variation in the Tafel slopes is an indication of change in reaction kinetics.…”

Five different water soluble terpolymers, namely polyvinyl alcohol-g-poly(acrylamidevinylsulfonate), polyvinyl alcohol-g-poly(acrylic acid-vinylsulfonate), polyvinyl alcohol-g-poly(acrylamide-vinyl benzene sulfonate), polyvinyl alcohol-g-poly(acrylic acid-vinyl benzene sulfonate) and polyvinyl alcohol-g-poly(vinylsulfonate-vinyl benzene sulfonate), have been designed, developed and tested for their efficacy to control N-80 steel corrosion in 10 % HCl, 3.5 % NaCl and simulated well water. The terpolymer characterization was carried out by FTIR. The inhibitors were tested by potentiodynamic and impedance techniques. The inhibitors were also tested in static and dynamic conditions at 55±5 °C, for 6 hours immersion period by weight loss method. Acrylamide terpolymers rendered the best inhibition efficiency in all the studied systems. The results provided a preliminary validation of the inhibitor such that they can be optimised and used for corrosion in oil and gas industries.
