糠醛对碳钢在盐酸中的缓蚀性能研究
Inhibition Performance of Furfural on Carbon Steel in Hydrochloric Acid
摘要
Abstract
As a corrosion inhibitor, the corrosion inhibition of furfural obtained from straws by microwave pyrolysis was investigated in hydrochloric acid solution. The weight loss and electrochemistry polarization evaluation, and the absorbance of furfural on carbon steel was preliminary discussed. The results showed that furfural, as a complex inhibitor, gives nice inhibition efficiency on carbon steel in hydrochloric acid medium. The inhibition efficiency of furfural was up to 91. 3 % when the mass fraction of furfural reaches 0.7 % at room temperature. It can also reduce the activation energy of corrosion reaction. This results in a decrease of corrosion rate. The inhibition performance of furfural is affected by temperature, and its absorbance behaviors can be expressed by the equation of Langmuir model.关键词
