The Department of Chemistry Discusses a Master’s Thesis on the Preparation and Diagnosis of New Nanomaterials and Studying Their Efficiency in Inhibiting the Corrosion of Carbon Steel
The Department of Chemistry at the College of Education for Pure Sciences at the University of Kerbala discussed a master’s thesis entitled (Preparation and Diagnosis of New Nanomaterials and a Study of Their Efficiency in Inhibiting the Corrosion of Carbon Steel) by the student (Ali Hassan Wadaa), under the supervision of the Dean of the College of Education for Pure Sciences, Prof. Dr. Hamida Eidan Salman, as the first supervisor, and Prof. Dr. Assem Alaa Abdel Hussein, as the second supervisor. The thesis aimed to prepare corrosion inhibitors for carbon steel in acidic environments by preparing selenium nanoparticles, attaching them to polymers (polyvinyl alcohol, chitosan) and diagnosing them using TEM techniques. DLS. Zeta potential. XRD. FT-IR. In addition to using the prepared nanomaterials to inhibit the corrosion of carbon steel at 1.0M H2SO4 and a temperature range (303k-323k) using electrochemical techniques. The thesis also included how to prepare environmentally friendly and stable selenium nanoparticles with polyvinyl alcohol (PVA-SeNPs) and chitosan (Ch-SeNPs) by chemical reduction method using ascorbic acid as a reducing agent and in the presence of polymers as covering agents. It explained the electrochemical analysis, weight loss method and surface study of carbon steel alloys. PVA-SeNps and Ch-SeNps are effective corrosion inhibitors of carbon steel in 1M H2SO4. Electrochemical analysis using the Tafel technique showed that the inhibition efficiency is directly proportional to the concentration and inversely proportional to the temperature. The study recommended focusing on the current study in order to expand future studies and use other types of alloys, as well as using other techniques to study the efficiency of nanoinhibitors, such as electrochemical impedance spectroscopy (EIS) studies. And using other polymers to stabilize selenium nanoparticles and studying their efficiency in inhibiting the corrosion of carbon steel and comparing it with the current study. The student received an excellent grade. To view the pictures:
