We find that the inhibition efficiency increases with inhibitor concentration and it attains an efficiency of more than 90% at 10-3 M. Polarization curves show that HPDTP is a mix-type inhibitor. Changes in impedance parameters were indicative of adsorption of HPDTP on the steel surface, leading to the formation of a protective film. Our findings will contribute to the development and application of novel corrosion inhibitors. © 2020 Author(s).en10.1063/5.0014570info:eu-repo/semantics/closedAccessCorrosion Inhibition; Electrochemistry; Mild steel; Triazolopyrimidine DerivativeConference Object22582-s2.0-85091897600N/A
