دراسة مقارنة لبعض المقالات العلمية حول تطبيقات الإلكتروكيمياء، (دراسة الفعالية المضادة للأكسدة والتآكل بالطرق الإلكتروكيميائية)

Résumé: The aim of this study is to compare some scientific articles on the applications of electrochemistry (estimate Antioxidant activity of phenolic extracts of dates (Phoenix dactylifera.L) cultivares, and the anti-corrosion activity of some plant extracts). The antioxidant activity was studied using cyclic voltammetry to determine the antioxidant capacity of the extracts on the inhibition of the superoxide anion radical O2 •−, where the results showed that the methanolic extracts have the ability to inhibit the free radical O2 •− in all studies, Where Degla Al Hamra (DR) for the study of Ben Tabbah was recorded a high ability to inhibit free radical O2 •−, with an IC50 value was 0.006g/l. The anti-corrosion activity of HCl at a concentration of 1 M and 0.5 M was studied in several ways, including: Polarization curves and electrochemical impedance spectroscopy. The results obtained are proven recording the highest inhibition rate in the polarization curves method for the study of Ibtissam BEL Aouar for plant extracts Senecio hoggariensis Batt. & Trab, which was estimated 97.40% at a concentration value was 12.5ppm, while the highest inhibition rate was estimated 97% at 1400 ppm concentration for date seed extracts in the impedance spectroscopy method for the study of Naba Jasim Mohammed & Norinsan Kamil. Through these results, it was proven that there is a high effectiveness of date extracts that differ according to the cultivar and planting area, and plant extracts also have the ability to inhibit corrosion.
