The aim of this work is to develop new organic bio-sourced inhibitors that are ecofriendly and biodegradable. These natural inhibitors are organic, non-toxic molecules derived from plant extracts, containing numerous secondary metabolites, and are capable of being highly effective in protecting metals against corrosion. This study concerns the extr...

Context 1
... extractions on the ground and unground Sargassum fluitans III, using water/ethanol as cheap and green solvent, were used to obtain the extract algae. The reflux extraction on the ground algae gave the high yield using (70:30) water/ethanol as shown in Table 1. However, the constituents of organic compounds in the extract were the same for different ratios for the ground and unground algae; Figure 1. ...Context 2
... indicated in Table 1, the corrosion current density consistently decreases with increasing concentration, notably surpassing the values observed in uninhibited acidic solutions. The inhibitor efficiency exhibited an upward trend with increasing inhibitor concentration, reaching its maximum at 200-300 mg L −1 . ...Context 3
