In this article, research has been conducted on obtaining an eco-friendly inhibitor and its application in practice. The source of the green inhibitor is the Salsola oppositifolia plant, from which the method of obtaining the green inhibitor extract is studied. The obtained extract is studied as a green inhibitor in 0.5 M HCl solution for corrosion protection of carbon steel structures. In determining the efficacy of a green inhibitor derived from the Salsola oppositifolia plant, practical experiments have been performed at two different temperatures (298 K and 313 K) and at different concentrations (200 mg/L , 400 mg/L, 600 mg/L, and 1000 mg/L). Adsorption of green inhibitor on steel surface has been studied using Langmuir and Temkin isotherms. The effect of temperature and concentration on the corrosion rate is also studied. The gravimetric method is used to determine the effectiveness of the green inhibitor and it is found that its maximum concentration is 91.86%. The mechanism of action of the steel surface and a post-experimental steel sample are studied by scanning electron microscope analysis. Salsola oppositifolia extract is a good green inhibitor due to the presence of hetero atomic organic compounds in the main component.

Adsorption of green inhibitor on steel surface has been studied using Langmuir and Temkin isotherms. The effect of temperature and concentration on the corrosion rate is also studied. The gravimetric method is used to determine the effectiveness of the green inhibitor and it is found that its maximum concentration is 91.86%. The mechanism of action of the steel surface and a post-experimental steel sample are studied by scanning electron microscope analysis. Salsola oppositifolia extract is a good green inhibitor due to the presence of hetero atomic organic compounds in the main component.
