Numerical analysis of the inhibition effect of Commiphora myrrha and Cymbopogon nardus plant extracts on low carbon steel corrosion in simulated industrial environment

The corrosion inhibition properties of specific concentrations Commiphora myrrha (CM), Cymbopogon nardus (CN) green chemical compounds and their combined admixture (CMCN) on low carbon steel in dilute H2SO4 HCl solution was studied by weight loss analysis. Results show CM performed poorly at (0.5% − 1.25% CM) with optimal value 51.41% compared to CN which effectively all generally above 85%. Performance compound were similar. Both exhibited poor efficiency below 60% 0.75% concentration). At higher concentrations, efficiencies 70%, values 83.05% 96.07% 1.5% 1.75% concentrations. Admixture inhibitor This contrast the observation it 80%. Statistical analysis through ANOVA shows concentration is only statistically relevant variable influencing performance outputs inhibitors 92.29% 88.48% for H2SO4, 41.40% 95.25% HCl. Values CMCN are 69.57% 4.69% solution. Standard deviation calculations 33% 98% + 11.93% 3.24%% margins error 25% 53% 10.96% ± 12.62% 80% effective threshold value. 0% 100% threshold.
