Different electrochemical techniques, such as electrochemical “impedance spectroscopy (EIS), electrochemical frequency modulation (EFM), and potentiodynamic polarization (PDP), and mass reduction at various temeratures were used to evaluate the inhibitory potential of Terfeziaceae extract as a corrosion inhibitor for Cu in HNO₃ corrosive arrangements. The adsorption was analyzed utilizing Temkin adsorption isotherm, and the adsorption factors were considered. The detections illustrated that the Terfeziaceae extract shown maximum inhibition capacity (% IE) reached to 98.1% at concentration of 300 ppm, 25°C. “x-ray electron spectroscopy (XPS), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) surface study techniques have all supported the existence of a protective layer on the Cu surface. This extract operates as a mixed-type inhibitor, according to PDP data.” The current research presents highly significant findings in the preparation and design of original, environmentally friendly, sustainable inhibitors with high inhibitory power.

Terfeziaceae植物提取物对铜硝酸分解的抑制作用

使用不同的电化学技术，例如电化学“阻抗谱（EIS）、电化学频率调制（EFM）和动电位极化（PDP）以及不同温度下的质量还原来评估Terfeziaceae提取物作为Cu腐蚀抑制剂的抑制潜力。在 HNO ₃腐蚀性装置中。利用Temkin吸附等温线对吸附进行分析，并考虑吸附因素。检测表明，Terfeziaceae提取物在浓度为300 ppm、25°C时表现出最大抑制能力（％IE）达到98.1％。 “X 射线电子能谱 (XPS)、扫描电子显微镜 (SEM) 和傅里叶变换红外光谱 (FTIR) 表面研究技术都支持铜表面存在保护层。根据 PDP 数据，这种提取物可作为混合型抑制剂。”目前的研究在制备和设计具有高抑制能力的原创、环保、可持续抑制剂方面取得了非常重要的发现。
