摘要

本研究旨在采用电位极化和电化学阻抗光谱(EIS)等实验方法,研究仙人掌果 Mammillaria prolifera 的水提取物在 1.0 M HCl 溶液中的吸附和腐蚀行为。Mammillaria prolifera 是仙人掌科仙人掌属植物,俗称德克萨斯乳头仙人掌。实验对四种不同的 Mammillaria prolifera 果实进行了水提取。结果表明,仙人掌果实的水提取物溶液在最佳浓度为 0.120%(w/v)时,抗腐蚀性能超过 90%。除电化学实验外,FE-SEM 表面图像也是高抑制性的另一个指标。结果表明,与不含抑制剂的表面相比,在 298 K 下浸入抑制电解质溶液一小时后的低碳钢表面没有出现裂纹、凹坑或变形。因此,实验测量结果和 FE-SEM 表面图像相互印证。

INSIGHT INTO ANTI-CORROSION EFFECT OF MAMILLARIA PROLIFERA FRUIT EXTRACT AS A GREEN INHBITOR FOR MILD STEEL IN HCl SOLUTION
In this study, it was aimed to examine the adsorption and corrosion behaviours of the aqueous extract of Mammillaria prolifera, a cactus fruit, in 1.0 M HCl solution using experimental methods such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Mammillaria prolifera is a cactus species from the Cactaceae family, commonly known as Texas nipple cactus. Experiments were realized for aqueous extracts of four different Mammillaria prolifera fruits. The results indicate that the aqueous extract solution of cactus fruit has outstanding anti-corrosive performance of over 90% at the optimum concentration of 0.120% (w/v). In addition to electrochemical experiments, FE-SEM surface images were taken as another indicator of high inhibition. The results showed that the mild steel surface immersed in the inhibited electrolyte solution at 298 K after one-hour exposure did not contain cracks, pits or deformations compared to the inhibitor-free surface. As a result, experimental measurements and FE-SEMsurface images support each other.
