The ethanolic extract of the Arum italicum plant is a good corrosion inhibitor of ordinary steel in a 3% HCl solution and their efficiency depends on the concentration and temperature. The electrochemical study by polarization gives an excellent efficiency of 97.85% for a concentration of 750ppm which is in good agreement with the data obtained from EIS (97.21%). The polarization curves for the steel electrode show that the extract is of mixed type. The adsorption of this inhibitor on the steel surface follows the Langmuir isotherm and physisorbed on this surface. Green synthesized of Ag nanoparticles product shows a very significant photocatalytic activity where The photocatalytic degradation efficiency of about 98% observed for Ag NPs in the presence of 150 min of sunlight irradiations. So these observed results strongly indicate that Ag NPs are photocatalytically active under sunlight irradiation. It indicates that sunlight irradiation highly induces the photocatalytic process of Ag NPs. The antimicrobial activity results, reveal significant inhibition diameters for different concentrations of the substance tested against E. coli, S. aureus, and P. aeruginosa.. Silver nanoparticles demonstrated efficacy against both gram (+) and gram (-) bacteria, confirming their antimicrobial potential. In addition, a reduction in microbial growth was observed with increasing nanoparticle concentration. ordinary steel Arum italicum plant extract anti-corrosion Green synthesized of Ag nanoparticles photocatalytic antimicrobial activity Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Full Text Additional Declarations No competing interests reported.
