ABSTRACT
The inhibitive strength of
Canonamuricata (CM) and Cassuttidfilifurmis (CF) on mild steel
dissolution in 0.5 M H 2 SO 4 and 1 M HCl environment was studied using gravimetric and
electrochemical techniques. The results obtained indicate that all studied extracts of both plants are adsorption type inhibitors hence; t he adsorption of the inhibitors is in line with Langmuir
adsorption isotherm. Efficiencies of the inhibitors increased with an increase in concentration of the extract but decreased with increase in the period of immersion. Polarization findings showed
that the inhibitors affected both the cathodic and anodic half reactions and are regarded as a
mixed type in the acidic environments investigated . From the studies so far, maximum inhibition
efficiency values of 95.1%, 94.1% and 94.2%, 89.2% were obtained in 0.5 M H 2 SO 4 and 1 M
HCl environments for CM and CF. R Regression coefficient (R2) of 0.9892, 0.9994 and 0.9877, 0.9987 was obtained for CF and CM in HCl and 0.5 M H2SO4.
