UV-assisted isomerization studies of active compounds in bush tea (Athrixia phylicoides) leaf extracts and investigations of their potential to inhibit acid corrosion of mild steel and zinc
type: CreativeWork
description: Corrosion of metals can be controlled by using corrosion inhibitors. Plant metabolites undergo geometrical isomerization under the influence of UV light radiation. The use of corrosion inhibitors is one of the useful methods to reduce or decrease corrosion on metals. While synthetic inhibitors are useful in preventing the corrosion of metals, they can sometimes be harmful and costly. There is an alternative solution in the form of green inhibitors, which can offer the same level of protection at an affordable price. Inhibitors of corrosion are applied to the environment and the metal they protect against deterioration. Considering this information, it is necessary to examine different metals exposed to an acidic environment in the presence and absence of inhibitors. The impact of UV light radiation on bush tea (A. phylicoides) plant extract was investigated for zinc, and mild steel corrosion exposed to 1.5 M hydrochloric and sulphuric acids at 303-333K. This study employs liquid chromatography-mass spectrometry (LC-MS) to investigate the geometric isomerization of compounds within plant extracts, aiming to identify and quantify different isomers and understand the conditions influencing their stability and transformation. Gravimetric analysis (GA), Electrochemical Impedance Spectroscopy (EIS), and Potentiodynamic Polarization (PDP) were used to study corrosion inhibition, Fourier Transform Infrared Spectroscopy (FTIR) was used to analyze functional groups in the presence and absence of corrosion inhibitors. Contact angle or wettability studies (CA / WS) have been conducted to assess the hydrophobicity or hydrophilicity of the surface. Scanning Electron Microscopy (SEM) and computational studies were employed to gain a deeper understanding of the surface morphology and interactions between the A. phylicoides plant extracts and the metal surface. LC-MS chromatograph shows that the extract undergoes geometric isomerization. The GA, EIS, and PDP tests showed that the ex…
