Eco-Friendly Corrosion Inhibition of Pipeline Steel UsingBrassica oleracea

Abstract

The inhibition capacity of Brassica oleracea (BO) extract on the corrosion of pipeline steel in 0.5 M H 2 SO 4 was evaluated using electrochemical techniques. The results showed an excellent inhibition efficiency which increased with initial increase in extract concentration and temperature to a point and decreased with further increase in BO extract concentration and temperature. Mixed inhibition behaviour was proposed for the action of BO. The unique behaviour of BO was attributed to the organic entities present in the extract.

A New Insight into Non‐Steroidal Anti‐Inflammatory Drugs (NSAIDs) as Modulated Green Inhibitory Agent on Mild Steel Corrosion

“…I corr values were found decreasing with increase in concentration without causing any significant changes there by suggesting that the existence of drugs retard the electrochemical reaction on MS surface due to the protective ( barrier ) layer of NSAIDs on MS surface which increases %IE ,,. Apparently from Figure , the nature of the polarization curves remained the same in the absence and presence of NSAIDs.…”

Corrosion Pattern of Pipeline Steel in Petroleum Pipeline Water in the Presence of Biomas Derived Extracts of <i>Brassica oleracea</i> and <i>Citrus paradise</i> Mesocarp

“…The steel coupons for the experiments were polished successively with emery paper from 150 to 2000 grits and rinsed with ethanol. Acetone was ap- [16]. All other reagents used were of analytical grade.…”

Adsorption and corrosion inhibition characteristics of two medicinal molecules

“…However, depending on the mechanism of adsorption some inhibitors get desorbed with rise in temperature. Our research group has earlier explained that optimal corrosion inhibition efficiency is attained at optimal interaction between corrosion inhibitor molecules and atoms at metallic surface (Ngobiri et al, 2015). Figure 13 shows a comparison of corrosion inhibition efficiency of various concentrations Phenylalanine and Rutin for the corrosion of mild steel in 1.0 M HCl environment.…”
