摘要

The extract of henna (Lawsonia Inermis) leaves have been evaluated as a green corrosion inhibitor forcarbon steel (C-steel) in 1M HCl solution, utilizing mass loss (ML), potentiodynamic polarization (PP),AC impedance spectra (EIS) and electrochemical frequency modulation (FEM) techniques. The surfaceanalysis was performed using energy dispersion spectroscopy (EDX) and scanning electron microscopy(SEM) methods. The inhibiting property of the extract is familiar with the presence of Lawsonia as amajor constituent in the extract. PP study revealed that the adsorption of the extract affects both anodicand cathodic reactions. The inhibitor efficiency (IE %) was found to improve with rising the extractconcentration and reached 83.1% at 300 ppm. On the other hand, the PE% was lowered by raising thetemperature. The adsorbed Henna molecules on C-steel obeys Langmuir isotherm. The results achievedby different tests are close to each other.
