Abstract

The efficiency of Lepidium didymium’s aerial part for corrosion inhibition, has been explored by applying weight loss
analysis, SEM, and spectroscopy technique on mild steel corrosion in 1 M H2SO4 . These techniques have been used to
investigate the corrosion features of the steel in the absence and existence of various quantities of Lepidium didymium’s
extract. With the aid of weight-loss statistics, the ability of the plant extract to construct a defensive film on steel surfaces is
investigated. The formation of a protective membrane on the steel surface by the extract has also been supported by a
surface morphology analysis (SEM). At 2500 mg/L, plant extract has the best inhibitory efficiency for steel in 1 M H2SO4
is 91.16%. Lepidium didymium extract is thought to be an effective inhibitor because of the presence of heteroatoms and
multiple bonds
