Discussion of a Master’s Thesis
The Department of Chemistry at the College of Education for Pure Sciences / University of Karbala discussed the master’s thesis entitled (Inhibition of corrosion of different alloys in the acidic medium using the Nile flower), by the student (Saja Ahmed Abdel Karim Abdel Rahim), and under the supervision of: Dean of the College of Education for Pure Sciences, Prof. . Hamida Idan Salman, and Prof. Dr. Sajid Hassan Kazar. The thesis aims to prepare some plant extracts as green inhibitors for the corrosion of carbon steel in an acidic medium, prepare the inhibitors from the roots of the Nile flower using the saxolites device, and perform a gas chromatographic mass spectrometry (GC-MS) analysis.
The thesis showed that we can prepare the polar extract of the methanol solvent and the non-polar extract of the hexane solvent as effective and good corrosion inhibitors for the corrosion of carbon steel in the acidic medium (1M HCl). By comparing the two inhibitors at a temperature of (303K) it was found that the inhibition efficiency of the polar extract is higher than that of the non-polar extract. polar. The researcher recommended extracting similar compounds but from other branches of the flower such as (the stem or leaves), using other temperatures and concentrations and comparing them, using other types of alloys, using other multiple media such as acidic, basic or neutral, and using other methods to study the corrosion process on the metal alloy. The student received an honors grade.
