“…This resulted in www.bosaljournals/chemint/ editorci@bosaljournals.com good corrosion inhibition capacity of S+P. This behaviour has been severally reported (Huang et al, 2013;Johnsirani et al, 2013;Ngobiri et al, 2015). The corrosion inhibition efficiency of S+P increased with increase its concentration.…”

The anti-corrosive properties of sulphadoxine + pyrimethamine (S+P) on the corrosion of pipeline steel in acidic environment were investigated using electrochemical techniques. The results obtained showed an excellent inhibition efficiency which increased with increase in inhibitor concentration. The corrosion inhibition efficiency increased up to 99.04 % at 0.01M S+P and decreased with rise in temperature down to 85.93 % at 333 K and 0.01 M S+P, suggesting a physiosorptive mechanism of adsorption. Also the adsorption data was fitted into Langmuir and Temkin adsorption isotherms, while the inhibitive action was shown to proceed by mixed inhibition mode.

“…However, the chromate and nitrite based compounds that had been found as effective inhibitors of steel-rebar corrosion in these studies suffer the setbacks of limitation and restriction on the usage of the substances due to their toxicity and environmental hazardousness [14][15][16]. Apart from the toxicity and hazardousness to the environmental ecosystem, these inorganic, synthetic chemical inhibitors also hardly fulfil the important conditions of easy availability and cost effectiveness [17,18]. These necessitate search for environmentallyfriendly, easily available, cost effective and green alternatives for addressing the problems of corrosion degradation of steel reinforced concrete in the acidic sulphate environment.…”

Electrochemical monitoring techniques were employed in this study to assess anticorrosion performance of Phyllanthus muellerianus leaf-extract on concrete steelreinforcement in 0.5 M H 2 SO 4 , used for simulating industrial/microbial environment. For this, steel-reinforced concretes admixed with different concentrations of the natural plant leaf-extract were partially immersed in the acidic test-solution and subjected to electrochemical monitoring of corrosion potential, corrosion current and corrosion rate. Test responses analysed as per ASTM G16-95 R04, showed that the corrosion rate correlated, r = 84.93%, ANOVA p-value = 0.0403, with the leaf-extract concentration admixed in concrete and the ratio of the standard deviation of potential to the standard deviation of current. These identified the 0.3333% Phyllanthus muellerianus (per weight of cement) with optimum effectiveness at inhibiting steel-reinforcement corrosion both by the experimental model, η = 91.66±2.51%, and by the prediction from the correlation fitting model, η = 85.54±14.44%. Fittings of both the experimental and the predicted data followed the Flory-Huggins and the Frumkin adsorption isotherms which suggest prevalent mechanism of physical adsorption (physisorption) of the extract on steel-rebar surface. These support the use of Phyllanthus muellerianus as environmentally-friendly admixture for inhibiting concrete steel-reinforcement corrosion in the industrial/microbial service-environment.
