The corrosion inhibition nature of Cuscuta reflexa fruit extract, belonging to the family of Piperaceae, has been analyzed on mild steel in 0.5 M H₂SO₄ with the help of weight loss studies, potentiodynamic polarization, and electrochemical impedance spectroscopy techniques. The C. reflexa extract contains 3‑methoxy‑3,4,5,7‑tetrahydroxy flavone, which decreases the corrosion rate of mild steel in acidic medium. The maximum corrosion inhibition efficiency was observed at 500 mg/L inhibitor concentration. The adsorption study of C. reflexa extract on mild steel surface has been conducted using UV, FTIR, AFM, SEM, and DFT.

s丝提取物对0.5 MH ₂ SO ₄对低碳钢的缓蚀作用和吸附活性的研究

借助减重研究，电势极化和电化学阻抗谱技术，已经在0.5 MH ₂ SO _4的低碳钢上分析了属于胡椒科的反射小瓜（Cuscuta reflexa）果实提取物的缓蚀性能。所述C. reflexa提取物包含3-甲氧基3,4,5,7-四羟基黄酮，这降低了低碳钢在酸性介质中的腐蚀速率。在抑制剂浓度为500 mg / L时观察到最大的腐蚀抑制效率。使用UV，FTIR，AFM，SEM和DFT进行了反射小球藻提取物在低碳钢表面的吸附研究。
