The study of the inhibitory power of the Pulp of Jujube (PJ) extract of the plant Zizyphus Lotus with respect to the corrosion of copper in 1 M hydrochloric medium has been realized. This study was conducted by stationary and transients electrochemical measurements, weight loss and atomic absorption spectroscopy techniques. Scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS), Fourier transform infrared (FT-IR) and atomic force microscopy (AFM) studies were used to characterize the surface of uninhibited and inhibited copper specimens. The results showed that the inhibition increases with PJ extract concentration reaching a maximum of 93% at a concentration of 1 g L⁻¹. The obtained results indicate that PJ extract can act as a good green corrosion inhibitor for copper in 1 M HCl. The effect of temperature was also investigated and thermodynamic parameters were determined and discussed.

已经实现了对植物Zizyphus Lotus的枣浆提取物对铜在1 M盐酸介质中的腐蚀的抑制能力的研究。这项研究是通过静态和瞬态电化学测量，重量损失和原子吸收光谱技术进行的。扫描电子显微镜（SEM），能量色散X射线光谱（EDS），傅立叶变换红外（FT-IR）和原子力显微镜（AFM）研究用于表征未抑制和抑制的铜样品的表面。结果表明，当浓度为1 g L ^-1时，PJ提取物的浓度最高达到93％时，抑制作用增加。所得结果表明，在1 M HCl中，PJ提取物可作为铜的良好绿色缓蚀剂。还研究了温度的影响，并确定和讨论了热力学参数。
