    (THE ANNALS OF “DUNAREA DE JOS” UNIVERSITY OF GALATI, 2023) Yusuf Lanre, Shuaib-Babata; Israel, Ayinde; Yusuf, Busari; Mubarak, Ameen; Raheem Abolore, Yahya; Ibrahim Owolabi, Ambali; Ishaq, Aremu; Sikiru, Abdulraman; Kabiru Suleiman, Ajao; Abdulateef, Garuba
    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%).

    Inhibitive Potential of Prosopis Africana on Corrosion of Low Carbon Steel in 1M Hydrochloric Acid Medium
    (Deer Hill Publications, 2019) Yusuf Lanre, Shuaib-Babata; Hassan Kobe, Ibrahim; Ibrahim Owolabi, Ambali; Raheem Abolore, Yahya; Ishaq, Aremu; Kabiru Suleiman, Ajao; Abibat, Pelumi
    Recently, there is quest for the use of inexpensive, non-toxic, non-biodegradable, readily available and environmentally acceptable corrosion inhibitor. Studies have shown that these properties could be achieved through the use of plants as inhibitor. Inhibiting effect of Prosopis Africana (Iron Tree) seed extracts were assessed on a sample of low carbon steel in 1M HCl with varying proportion of the seed extract using gravimetric, Tafel polarization and gasometrical measurement techniques. The results show that weight loss/corrosion rate decreases with increase in the extracts’ concentrations. Good inhibiting efficiency of Prosopis Africana extracts with optimum inhibiting efficiency of 97.7% at 1.0 g/l after 120 hours exposure in gravimetric measurement was attained. TAFEL polarization results revealed that the Prosopis Africana extract shows that the corrosion current density decreases with the increase in the concentration of the extract. The extract is found suitable as green inhibitor for corrosion of low carbon steel in the studied medium.
