Дослідження впливу розчинника на протикорозійну ефективність екстракту жмиха абрикосу

Abstract

The apricot pomace was introduced as a sustainable corrosion inhibitor with excellent inhibition action for mild steel in sodium chloride solution. The results showed that the extracting solvent significantly altered the inhibition property. The present study shows that the ethanol, propan-2-ol and mixed ethanol/propan-2-ol of apricot pomace extracts can be used as an effective inhibitors for the carbon steel corrosion in 0.5M NaCl solution. Compared with EAPE and E/PAPE, the PAPE is more effective. It is therefore pertinent to conclude that the high inhibition efficiency of propan-2-ol extract in comparison to EAP and E/PAP extracts observed in the present study could be attributed high phytochemical constituents of aldehydes and terpene alcohols. The electrochemical technique of cycling voltamperometry was used to investigate the reducing ability of the extracst.
