Authors are strongly advised to ensure that the submission falls under the scope of the journal and that all guidelines related to manuscript preparation are adhered to before submission.</p> <p>Accepted manuscripts are published freely under the Creative Commons Attribution Non-Commercial 4.0 International (CC BY-NC 4.0) license.</p> <p>Authors retain copyright.</p> en-US ujpicr@umyu.edu.ng (Dr. Yusuf Hassan ) maryam.saddiq@umyu.edu.ng ( Maryam Saddiq) Mon, 18 Aug 2025 14:16:48 +0000 OJS 3.3.0.12 http://blogs.law.harvard.edu/tech/rss 60 https://ujpicr.umyu.edu.ng/index.php/ujpicr/article/view/47 By utilizing electrochemical technique, the corrosion inhibition efficiency of Anacardium occidentale leave extracts on Grade 304 austenitic mild steel in 1 M sulphuric acid solution was examined. The crude extract of Anacardium occidentale leaves was used in this study to screened the phytochemicals and examine its inhibitory qualities as a corrosion inhibitor for mild steel in 1M sulphuric acid media. The phytochemicals showed the existence of many phytochemicals were flavonoids and alkaloid provide the majority.The efficacy of Anacardium occidentale leave extracts inhibition increased with concentration while decreasing with temperature. At 0.7 g/L extract concentration for 3 hours of immersion, the inhibitor's greatest efficiency was 94%. Mild steel corrosion was successfully inhibited by Anacardium occidentale leave extracts, according to the results obtained, and it was discovered that the presence of halide ions enhanced the efficacy of the inhibition. The synergistic effect of halide ions was found to follow the order: KI >KBr>KCl. According to the electron impedence spectroscopy (EIS), Anacardium occidentale functions as a mixed-type inhibitor. Due to the extract components' adsorption on the mild steel surface, leave extracts exhibit an inhibitory effect. The activation energy of the corrosion reaction increases by the presence of both extract and halide ion. The results of a study using scanning electron microscopy to examine the surface morphology of mild steel in inhibited and uninhibited acid solutions revealed that the presence of extract and halide inhibitors remarkably lowers the corrosion rate.

Soil pH ranged from 6.05 in Tsamawa (KISS) to 6.30 in Kofar Sauri (KUSS). Water holding capacity varied between 40.65% in KUSS to 75.53% in Kaita (KSS), while cation exchange capacity ranged from 4.33 Cmol/kg (KUSS) to 6.43 Cmol/kg (KSS). Organic carbon was highest in KSS (2.43), followed by KISS (1.62), and lowest in KUSS (1.39). Organic matter values were 4.20 (KSS), 2.80 (KISS), and 2.40 (KUSS). Soil textures were clay-loam (KSS: 52.2% clay, 32.4% sand, 15.4% silt), sandy-clay-loam (KISS: 62.0% sand, 22.3% clay, 15.7% silt), and sandy-loam (KUSS: 70.3% sand, 14.4% clay, 13.8% silt). Heavy metal concentrations exceeded FAO/WHO limits for Cd, Cr, Mn, Ni, Pb, and Zn. KSS had the highest Cd (1.443 mg/kg), Cu (3.882 mg/kg), and Pb (1.749 mg/kg), while KUSS showed elevated Cr (2.948 mg/kg), Ni (1.193 mg/kg), and Zn (1.701 mg/kg). KISS had the lowest contamination. Fe and Cu remained within safe limits. The findings indicate potential health and environmental risks, requiring remediation and further investigation into pollution sources.
