With the current emergence of green chemistry to keep the environment safe, attention is being shifted towards using plant extracts as corrosion inhibitors. The inhibitive performances of Talinum triangulare leaf extract and Musa sapientum peel extract on the ZA-27 in 1.0 M and 1.5 M hydrochloric acid solutions were studied for 18 days using mass loss measurement. The corrosion inhibition effic...

The corrosion inhibition efficiency of the vasaka leaf extract for protecting mild steel in potable water (neutral aqueous medium) was studied by weight loss, Open circuit potential monitoring and potentiometric polarization methods. The inhibition test was performed in potable water rather than deionized water because inhibitors are normally applied in neutral and industrial waters. The extrac...

in this paper, the effect of penicillin g drug as a green corrosion inhibitor on mild steel in 1.0 mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (eis) and electrochemical noise (en) techniques. the inhibition efficiencywas found to increase with increasing inhibitor concentration. potentiodynamic polarizationmeasureme...

The present work is aimed at examining carbon steel oil pipelines corrosion using three natural extracts (Eruca Sativa, Rosell and Mango peels) that are used as inhibitors of different concentrations ranging from 0.05-0.1wt. %. Two sulphur compounds are used as corrosion mediums. Weight loss method was used for measuring the corrosion rate of the carbon steel specimens immersed in technical whi...

The aim of this present work is to study, the corrosion behavior of carbon steel in well water in the presence of sodium tungstate (ST)-Zn 2+ -N-(phosphenomethyl) iminodiaceticacid (NPMIDA) solutions. Electrochemical studies and FTIR spectral studies and weight loss study have been employed. It was found that the inhibition efficiency (IE) of ST (50 ppm)-Zn 2+ (10 ppm) was improved from 8% to 8...

Azadirachta indica (AZI, commonly recognized as “Neem”) is noteworthy both for its chemical and for its biological actions. It is one of the most fruitful sources of secondary metabolites in nature. To date, more than 300 natural products have been isolated from different sections of the tree, with new compounds added to the list every year. As a contribution to the current interest on green co...

In this work, electrochemical methods such as Tafel polarization and electrochemical impedance spectroscopy (EIS) were used to study the inhibition efficiency of Nettle leaves hydroalcoholic extract as a green corrosion inhibitor of API 5L carbon steel in 0.5 M H2SO4 solution. The results showed that the inhibition efficiency was increased with increasing the concentration of the extract and th...

The corrosion inhibition of mild steel in 0.5 M H2SO4 solution has been investigated using electrochemical methods, X-ray diffraction (XRD) and scanning electron microscope (SEM). The adsorption and inhibition action of acid corrosion of mild steel using cetyltrimethylammonium bromide (CTABr) and different halides (NaCl, NaBr and NaI) has shown synergetic effect. The results showed that the pro...

Economic losses due to corrosion are direct, as well as, indirect and affect the economy of country. Corrosion inhibitors are one of the widely used methods to control corrosion. Particular advantage of corrosion inhibitor is that often can be implemented or changed in situation without disturbing a process. Due to toxic nature and high cost of some inhibitors currently in use it is nearly to d...
