Adsorption and Inhibitory Effect of Artemisia Herba Alba Essential Oil on Corrosion of 304 Stainless Steel in Acid Medium

EasyChair Preprint 9833

Abstract

follow Langmuir adsorption In the present study, Artemisia herba-alba essential oil was investigated as green inhibitor for stainless steel corrosion in 1 M HCl solution. Aerial parts of Artemisia herba-alba was hydrodistilled, and the chemical analysis of essential oil extract has been studied using gas chromatography and GC-mass spectrometry. The effects of natural Artemisia oil on the corrosion of stainless steel were studied by the measurements of weight loss, electrochemical, and EIS polarisation. The results revealed an increase in inhibition efficiency through increasing the oil concentration. The oil compounds act as mixed-type inhibitors and adsorb by physisorption, isotherm.
