Abstract

An aqueous extract of Macaranga peltata leaves has been investigated as green corrosion inhibitor for mild steel in 1 M hydrochloric acid medium using gravimetric and electrochemical methods. The inhibition efficiency increased with an increase in the inhibitor concentration and temperature. The aqueous extract of Macaranga peltata leaves acts as mixed type of inhibitor. The adsorptions of the inhibitor on the metal surface occurred by chemisorptions and obeyed the Langmuir adsorption isotherm. The activation and thermodynamic parameters for corrosion and inhibition processed were evaluated.

盐酸介质中的软钢绿色腐蚀抑制剂Macaranga Peltata叶子的水提取物

摘要

已经使用重量分析法和电化学方法研究了Macaranga peltata叶片的水提物作为低碳钢在1 M盐酸介质中的绿色缓蚀剂。抑制效率随着抑制剂浓度和温度的升高而增加。Macaranga peltata叶片的水提取物起抑制剂的混合作用。抑制剂在金属表面的吸附是通过化学吸附发生的，并遵守了Langmuir吸附等温线。评价了用于腐蚀和抑制的活化和热力学参数。
