The Department of Chemistry Discusses a Master’s Thesis on the Study of Corrosion Inhibition of Carbon Steel Alloy in an Acidic Medium Using a New Nano-polymer

Discussion of a Master’s Thesis

The Department of Chemistry at the College of Education for Pure Sciences discussed the master’s thesis for student (Doaa Rostom Muhammad Ali) under the supervision of Prof. Dr. Hamida Idan Salman and the second supervisor Prof. Dr. Muhammad Nazem Bahgat for her thesis entitled (Study of corrosion inhibition for carbon steel alloy in acidic medium using a polymer). new nano). The aim of the study was:
1. Synthesis and characterization of a new nanopolymer by (FT-IR, H NMR 1, and AFM) techniques.
2. The use of nano-polymers in corrosion inhibition by studying the corrosion polarization curves of carbon steel in M1.0 of sulfuric acid solution.
3. Study of the corrosion inhibition efficiency of carbon steel using a new nanopolymer and the study of adsorption isotherms.

* The most important conclusions:
Through this study, it was shown that the graft co-polymer mixed with acrylic acid is a good corrosion inhibitor for carbon steel alloys in an acidic medium (1.0M H2So4).
1. It was found that the damping efficiency of the nanopolymer increases with the increase in the weight of the added acrylic, and the efficiency also increases with the decrease in temperature
2. Adsorption isotherms (Lankemayr, Freundlich, Taman) were used to study the adsorption of the inhibitor on the surface of carbon steel.
3. The activation energy increases with the increase in the weight of the inhibitor, but it is small, which indicates that the adsorption is physical adsorption.
4. The corrosion rate and wear current density of carbon steel alloys increase with increasing temperature.
5. Nanop-olymer is a low-cost and more economical polymer, so it is recommended to use it to inhibit the corrosion of carbon steel.
After extensive scientific discussion and listening to the student’s defense of her thesis, her research method, and her use of sources and references, the thesis was approved with honors. Congratulations to the student, her supervisors, the Department of Chemistry, and the College of Education for Pure Sciences for this great achievement, and God Almighty grants success.
