Palakkal, Leena published the artcileCorrosion inhibition properties of the extracts of Hemigraphis colorata against mild steel in acidic media, Application of Methyl docosanoate, the main research area is mild steel Hemigraphis colorata hydrochloric acid corrosion inhibition.
Corrosion inhibition activity of the methanolic extracts of the leaf and stem of the plant Hemigraphis colorata against mild in 1M HCl were studied by weight loss methods at different temperatures The chem. components present in the extracts were analyzed by GC-MS methods. From the results obtained it was concluded that the extracts possess good inhibition efficiencies. The efficiencies were found to increase with inhibitor concentration and decrease with increase in temperature Evaluation of thermodn. parameters reveals that the adsorption of extracts on the mild steel surface obeys Langmuir adsorption isotherm. The mechanism of adsorption was found to involve a combination of physisorption and chemisorption. Quantum chem. studies on the major components identified in the extract by GC-MS method is in agreement with the exptl. observations.
