Aloe vera (L.) Burm.F. (= Aloe barbadensis Mill.), a widely recognized medicinal plant, holds a prominent position due to its potent cosmetic and medicinal attributes. The objective of this work is to develop a new eco-friendly corrosion inhibitor for bronze B66 that is non-toxic, simple to apply, cost-effective, stable, and reversible. To achieve this goal, we initially devised an improved and cost-efficient method for extracting Aloe vera mucilage (AVM). Then we tested as corrosion inhibitor for bronze B66 in 3% NaCl using gravimetric measurements, electrochemical methods and Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-Ray analysis (EDX). The electrochemical assessments validated the findings from the gravimetric analysis and demonstrated that our inhibitor significantly modifies the electrochemical process mechanism at the B66/3% NaCl interface. The corrosion rate of bronze decreases with the inhibitor's presence, and its inhibitory effectiveness amplifies with higher concentrations, reaching an efficiency of 86% at 750 ppm. The mechanism of metallic copper and corrosion Acemannan inhibitor was explored through DFT studies and molecular dynamics simulation.

芦荟 (L.) Burm.F. （= Aloe barbadensis Mill .），一种广泛认可的药用植物，由于其有效的美容和药用特性而占据显着地位。这项工作的目的是开发一种新型环保型青铜 B66 缓蚀剂，该缓蚀剂无毒、使用简单、经济高效、稳定且可逆。为了实现这一目标，我们最初设计了一种改进且经济高效的方法来提取芦荟粘液（AVM）。然后，我们使用重量测量、电化学方法、扫描电子显微镜 (SEM) 以及能量色散 X 射线分析 (EDX) 来测试青铜 B66 在 3% NaCl 中的缓蚀剂。电化学评估验证了重量分析的结果，并证明我们的抑制剂显着改变了 B66/3% NaCl 界面的电化学过程机制。青铜的腐蚀速率随着抑制剂的存在而降低，并且其抑制效果随着浓度的增加而增强，在 750 ppm 时达到 86% 的效率。通过DFT研究和分子动力学模拟，探讨了金属铜和乙酰化甘露聚糖缓蚀剂的作用机理。
