تثبيط تآكل الحديد في الوسط 1M H2SO4 بتشكيل فلم من مستخلص أوراق الزيتون

Abstract EN

The aim of this study is to find a material or a technique to effectively inhibit the corrosion of iron in an acid medium of sulfuric acid (1M H2SO4).

It was found that a conventional aqueous extract of olive leaves (OLE) has a strong effectiveness in inhibiting the iron corrosion in (1M H2SO4).

The film which was formed over the surface of iron sample after immersing the sample in olive leaves extract for various periods of time (45 minutes, 90 minutes, 3 hours, 6 hours, 12 hours, 1day, 2 days, and 4 days) and in several temperature (25, 35 and 45oC) was tested.

The weight loss method, potentiometic method (tafel plots), cyclic voltammetry and atomic force microscopy (AFM) methods were used in the study Where the highest achieved inhibition efficiency (IE) was up to almost 95%
