    Metal corrosion continues to be a major problem for a variety of sectors, prompting the investigation of innovative and environmentally acceptable corrosion prevention techniques. This study examined the potential of Phoenix dactylifera (date palm) seed extract as a green corrosion inhibitor for mild steel in an acidic environment (HCl). The study thoroughly investigated the inhibitory effects of various extract concentrations (0.2–1.0 g/l) on corrosion rate and efficiency across exposure times of 168 hours using both gravimetric and Tafel polarisation methods. According to experimental findings, extract concentration and corrosion inhibition effectiveness were strongly correlated. Corrosion rates were significantly reduced at higher extract concentrations, supporting the extract's potential as a powerful inhibitor. From the results, optimum inhibiting efficiency of 96.4% with concentration of 1.0 g/l after 72 hours of exposure and 61.99% from 1.0 g/l extract were observed for gravimetric and Tafel polarization, respectively. By emphasizing the extract's capacity to adsorb components onto the steel surface and create a shield that prevents corrosion, the research also contributes to the evolving field of corrosion science through introduction of a natural and eco–friendly corrosion inhibitor

    Corrosion inhibition efficacy of hybrid organic extracts from prosopisafricana and citrulluslanatus on mild steel in acidic medium
    (Faculty of Engineering, “Dunarea De Jos” University of Galati Romania, 2023-03-15) SHUAIB-BABATA, Yusuf Lanre; Ayinde, I. V.; Busari, Y. O.; Ameen, M. O.; Yahya, R. A; Ambali, I. O.; Aremu, N. I.; Abdulraman, S. O; Ajao, K. S; Garuba, A. A.
    Each of Prosopis Africana pod extract (PAPE) and Citrulluslanatus (WMPE) performed quite well as green inhibitors in the electrochemical corrosion in acidic solution at ambient temperature in previous research. However, the hybridization of these compounds was varied with the concentration ratio in this study to optimize the efficiency of the green inhibitor in a hydrochloric acid medium using mild steel. The extraction process of the inhibitor samples was carried out with the Soxhlet apparatus using n-hexane as the solvent. Furthermore, the potential inhibition efficiency was monitored using various corrosion measurement techniques at room temperature. The inhibitive response of the extracts could be attributed to the adsorption of the extracts’ components on mild steel surface by physisorption mechanism according to the Langmuir adsorption isotherm model. The results revealed that inhibition efficiency (IE%) depends on the concentration of the extracts. The peak IE% values were obtained with a hybrid ratio of 3:1 (PAPE: WMPE) for gravimetric technique. The Tafel polarization and gasometrical measurement technique is 96.7%, 98.5% and 83.1% respectively at the concentration of 1.0 g/L, which are above the peak IE% for PAPE (93.7%, 80.96% and 77.8%) and WMPE (92.7%, 80.5% and 75.6%)
