Broad spectrum corrosion inhibition: corrosion and microbial (SRB) growth inhibiting effects of Piper guineense extract

Exploiting the Anticorrosion Effects of Vernonia Amygdalina Extract for Protection of Mild Steel in Acidic Environments

“…The impedance data given in Table 2 were gotten by fitting into an equivalent circuit model R s (Q dl R ct ) shown in Fig. 7, which has been used by other researchers to model the impedance response for the mild steel/acid system [31,[40][41][42].…”

“…Electrochemical measurements were conducted in a conventional three-electrode glass cell of capacity 400 ml using a VERSASTAT 400 complete DC Voltammetry and corrosion system with V3 studio software [31]. The working electrode was mild steel; the counter electrode was a graphite rod and a saturated calomel electrode (SCE) was the reference electrode.…”

“…Mild steel coupons of size 15 × 10 × 2 mm were cleaned as previously described in the gravimetric section and immersed for 3-h in 1 M HCl and 0.5 M H 2 SO 4 solutions without and with 1500 mg/L VA at 30 ± 1 •C, and then dipped in distilled water, left to dry in acetone, and examine with SEM machine [31].…”

Corrosion Inhibition and Adsorption Behavior of Extract of <i>Funtumia elastica</i> on Mild Steel in Acidic Solution

“…Oguzie et al [23] reported that acid extract of Piper guineense effectively reduced the corrosion of mild steel in both hydrochloric and tetraoxosulphate (VI) acid media. Also Patel and co-workers [24] have investigated the corrosion inhibition of mild steel by leave extracts of Wrightiatinctoria, Clerodendrumphlomidis and Ipomoeatriloba and the study revealed that the plants inhibited the corrosion of mild steel in 0.5 M H 2 SO 4 .…”

Corrosion Inhibition of Mild Steel in 0.5 M H₂SO₄ Using Ethanol Extract of <i>Funtumia elastica</i>

“…Extracts of Piper guineense [24,25], Telferiao ccidentalis, Azadirachta indica, Hibiscus sabdariffa [26], Ocimum gratissimum [27], Chamaemelum-mixtum, Nigella sativa L [28], Wrightiatinctoria, Ipomoeatriloba [7] and Lupinousalbus [29] have been investigated for their corrosion inhibition effects on different metals. All the studied extracts proved to be active against the corrosion of the studied metals.…”
