环保型缓蚀剂用于保护环境以及使用腐蚀性酸进行清洁的工业设备。采用失重法和电化学方法研究了单叶苍术叶对低碳钢在酸性介质中腐蚀的抑制作用。从失重法、浸泡时间和温度等方面研究，AML提取物的抑制能力随浓度的增加而提高。电化学研究数据解释了AML缓蚀剂在腐蚀介质中的作用类似于阴极型和阳极型缓蚀剂。AML萃取物在金属表面形成的吸附层符合Langmuir吸附等温式。通过扫描电子显微镜、能谱分析和傅立叶变换红外光谱分析，证实了MS表面保护膜的形成。所有技术都证明AML在1N HCl介质中是可以接受的缓蚀剂。
The eco-friendly inhibitor is used to safeguard the environment as well as the industrial equipments where corrosive acids are used for cleaning purposes. The inhibition ability of Atalantia monophylla leaves (AML) on the deterioration of mild steel (MS) in acid medium was investigated by mass loss and electrochemical techniques. The inhibition capability raised with rising the concentration of AML extract from weight loss method, immersion period and temperature studies. Electrochemical studies data explained in which AML inhibitor performed like cathodic and anodic type of inhibitor in corrosive medium. The adsorbed layer formed on the metal due to AML extract fulfilled the Langmuir adsorption isotherm. The formation of the protective film on the MS surface was acknowledged by SEM, EDS and FTIR. All the techniques proved AML as acceptable corrosion inhibitor in 1N HCl medium.
