Gongronema latifolium was used as a low-cost green inhibitor for mild steel by applying the weight loss method at 303–323 K. There was a decrease in percentage inhibition with temperature increase and a rise in inhibition efficiency with an increase in the concentration of inhibitor. The obtained results showed that Gongronema latifolium extract of methanol had percentage inhibition efficiencies in the range of 59.06–81.69%. Corrosion inhibition of mild steel showed a good fit to the Langmuir model compared to the Freundlich and El-Awardy adsorption models. Thermodynamics parameters, such as \( E_{\text{a}} \), \( Q_{\text{ads}} \) and \( \Delta G_{\text{ads}} \) were evaluated and showed that the mechanism of corrosion inhibition of mild steel by methanol extract of Gongronema latifolium was physisorption. The results of this work indicated efficient potentials of the methanol extract of Gongronema latifolium as a low-cost corrosion inhibitor in acidic media for mild steel, which could be applied to reduce corrosion of metals in industries.

弓形虫通过在303–323 K上采用失重法，被用作低碳钢的低成本绿色抑制剂。随着温度的升高，抑制百分率下降，随着抑制剂浓度的增加，抑制效率上升。 。获得的结果表明，弓形虫甲醇提取物的抑制百分率在59.06-81.69％之间。与Freundlich和El-Awardy吸附模型相比，低碳钢的缓蚀性能非常适合Langmuir模型。热力学参数，例如\（E _ {\ text {a}} \），\（Q _ {\ text {ads}} \）和\（\ Delta G _ {\ text {ads}} \）进行了评价，结果表明，弓形虫甲醇提取液对低碳钢的缓蚀机理是物理吸附。这项工作的结果表明，弓形虫的甲醇提取物在低碳钢酸性介质中作为低成本腐蚀抑制剂的有效潜力，可用于减少工业中的金属腐蚀。
