Electrochemical data and analysis of the protection effect of Citrus Sinensis on mild steel in weak acid electrolytes
Data on the protection effect of Citrus Sinensis oil extracts (CS) on mild steel in dilute H2SO4 and
HCl solution was studied. The extract sufficiently protected the steel in both acids with respect to
its concentration. CS performed more effectively in HCl compared to H2SO4. Inhibition performance
of the extract varied significantly with exposure time. The highest inhibition efficiency of
78.47% and 85.61% was attained at the highest extract concentration in both acids. Inhibition
efficiency in both acids decreased with respect to exposure time. Standard deviation showed
variation of CS inhibition efficiency was significant at low concentration. Data from numerical
assessment showed extract concentration is the statistically relevant factor inducing protection of
the steel with statistical relevance of 89.9% and 96.39%. Data showed 58% and 86% of inhibition
efficiency data in H2SO4 and HCl solution are above 70% inhibition value at margin of error of
±0.097 and ±0.068
