摘要
采用失重、开路电位和动电位极化技术，在室温下研究了甲氧苄氨嘧啶作为一种绿色的市售缓蚀剂对1.0 M H2SO4溶液中低碳钢的缓蚀作用。结果表明，所研究化合物的抑菌效果与抑制剂的浓度和性质有关。抑制效果随抑制剂浓度的增加而增加。极化结果表明，该化合物为混合型缓蚀剂。假设缓蚀剂在金属表面的物理吸附符合Langmuir吸附等温线。扫描电镜(SEM)和能量色散x射线能谱(EDX)结果证实，在低碳钢表面形成了保护层。
Evaluation of Trimethoprim Drug as a Green Corrosion Inhibitor for Mild Steel in 1.0 M Sulfuric Acid
The mitigation of mild steel corrosion in 1.0 M H2SO4 solution by trimethoprim drug as a green and commercially available inhibitor was studied at room temperature using weight loss, open circuit potential, and potentiodynamic polarization techniques. The results showed that the investigated compound's inhibition efficiency depended on the concentration and nature of the inhibitor. The inhibition efficiency was found to increase with the concentration of the inhibitor. The polarization result indicated that the compound behaved as mix type inhibitor. The inhibition is assumed to occur via physical adsorption of inhibitor on the metal surface, which obeyed Langmuir adsorption isotherm. The scanning electron microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDX) results confirmed the formation of a protective layer on the mild steel surface.
