Experiments were performed by immersing mild steel electrodes in acidic solutions containing different\rconcentrations of Plagiochila porelloides extract for 1 hour before each electrochemical measurement to equilibrate\rwith the aggressive solution. Liverwort extract showed a strong inhibitory effect as a result of 1 hour electrochemical\rexperiments, and as the extract concentration increased, the protective effect of mild steel in acidic solutions raised. In\raddition, the surface images of the electrodes in 1.0 M HCl solutions with and without liverwort extract after 1-hour\rexposure were examined by an optical microscope and it was shown that the metal surface in the inhibited extract\rsolution had a smoother appearance compared to the uninhibited metal surface. Electrochemical findings and surface\rimages support each other.eninfo:eu-repo/semantics/openAccessYeşilSürdürülebilir Bilim ve TeknolojiKimyaUygulamalıMalzeme BilimleriÖzellik ve TestÇevre BilimleriFizikokimyaMalzeme BilimleriBiyomalzemelerArticle7211913010.26672.anatolianbryology.984722532468
