The inhibitory effect of moss extract was investigated applying the electrochemical impedance spectroscopy (EIS)technique. Nyquist diagrams were performedby EIS to examine the variation of the different concentrations of the extract with some immersion-time parameters. Also, the surface charge of the metal in terms of the inhibition mechanism was determined by the EIS technique and as a result, it was found that the protonated inhibitor molecules were adsorbed directly onto the metal surface.The surface morphology studies of working electrodes wereperformed using field emissionscanningelectronmicroscope(FESEM)andopticalmetalmicroscopytechniques. Electrochemical tests and surface analysis studies support each other.eninfo:eu-repo/semantics/openAccessBiyolojiMantar BilimiMalzeme BilimleriÖzellik ve TestEkolojiA New Inhibitor Approach to the Corrosion of Mild Steel in Acidic Solution with Long-Term Impedance Tests: A New Application Area for Hypnum cupressiforme(Bryophyta)Article6211912810.26672/anatolianbryology.767714418221
