“…This occurrence has been reported elsewhere [18,24]. In the presence of the extract, the inhibition efficiency increased up to a temperature of 303 K, and after that there was a decline from 318 -348 K. Maximum inhibition efficiency was found to be 97.70% and minimum of [25,26,27], adsorption and desorption of inhibitor molecules continuously occur at the metal surface, and an equilibrium exists between these two processes at a particular temperature. This shows that there is an active-passive region in the corrosion process of mild steel in the studied environment.…”

The feasibility of using extract of Grewa Venusta (wild jute tree) root as corrosion inhibitor with mild steel was investigated using gravimetric and electrochemical techniques in . The results showed that corrosion rate increased with an increase in temperature, and decreased with an increase in inhibitor's concentration and time; maximum inhibition efficiency was 97.60% and 99.88% in the presence of KI -addition, and was assumed to occur via adsorption of the inhibitor molecules on the metal surface. The extract contains metallic elements such as calcium, magnesium, mono acetate (C5H10O4) and 4H-Pyrazole (C9H10F6N2S) that suppressed the anodic dissolution. The adsorption of the extract molecules on the mild steel surface obeys Langmuir adsorption isotherm. The results showed that the inhibitor acted as a mixedtype inhibitor.

“…To calculate the surface coverage θ it was assumed that the inhibitor efficiency (IE%) is due mainly to the blocking effect of the adsorbed species and hence (IE% = θ × 100) [33]. In order to gain insight into the mode of adsorption of the extract on carbon steel surface, the surface coverage values from EFM technique were theoretically fitted into different adsorption isotherms and the values of correlation coefficient (R 2 ) were used to determine the best fit isotherm.…”

The inhibitive effect of the Euphorbia Helioscopia linn. extract (EHE) on the corrosion of copper in 1 M HNO 3 has been evaluated by means of potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) techniques. The calculated adsorp tion thermodynamic parameters indicated that the adsorption was a spontaneous, exothermic process accompanied by an increase in entropy. The inhibition efficiency increases with increasing the concentration of the inhibitor in the medium and decrease with increasing the temperature. The maximum inhibition approached to 91% in the presence of 500 ppm EHE using Tafel polarization technique. The results show that EHE is an effective corrosion inhibitor for protecting the corrosion of copper in 1 M HNO 3 medium even at stimulated conditions.

A series of new Schiff's bases containing 3,4-dimethyl maleimide moiety have been synthesized via multisteps synthesis including reaction of 3,4-dimethyl maleic anhydride with aniline producing N-phenyl-3,4-dimethyl maleimide which react with chlorosulfonicacid producing 4-(N-3,4-dimethyl maleimidyl ) phenyl sulfonyl chloride which on amination with hydrazine hydrate yielded in turn 4-(N-3,4dimethyl maleimidyl) phenyl sulfonyl hydrazine and this when condensed with various aromatic aldehydes and ketones afforded the desirable Schiff bases.Structures of the prepared compounds were confirmed by spectroscopic methods including FTIR, 1HNMR,C13NMR spectroscopy and C.H.N analysis. The synthesized Schiff's bases were screened for their antibacterial activity against three microorganisms: Staphylococcus aureus, Escherichia Coli, and Psedomonas aeruginosa. They were found to exhibit high antibacterial activity.
