دراسة تثبيط تآكل الحديد في الأوساط الحمضية باستخدام مستخلص قشور الرمان

Abstract

• In this research, the inhibiting effect of pomegranate peel extract on the corrosion of non-galvanized iron was studied by immersing the iron in a hydrochloric acid solution for 24 hours.
• The corrosion rate was calculated using weight loss methods and surface studies using electron microscopy.
• The structure of the chemical compounds extracted from pomegranate peels was identified using spectroscopic techniques (UV, IR).
• It was found that increasing the concentration of pomegranate peel extract led to an increase in charge transfer resistance due to the adsorption of the extract onto the iron surface.
• The study demonstrated that the increase in IE% with increasing concentration is due to the chemical adsorption of the extract onto the non-galvanized iron surface.
