摘要

摘要:采用失重法和动电位法考察了菠萝冠提取物在1M H2SO4酸性介质中对铝的缓蚀效果。通过失重法的数据，计算了不同缓蚀剂浓度下菠萝冠提取物在酸性介质中的腐蚀速率和对铝的缓蚀作用。利用动电位法获得的数据，构建极化曲线和Tafel切线，计算菠萝冠提取物的腐蚀速率和缓蚀效率。实验结果表明，菠萝冠提取物具有混合抑制剂的作用，且随着提取物浓度的增加，抑制效果逐渐提高。

Study of corrosion inhibition of aluminum in acidic media by pineapple crown extract

Abstract The efficiency of pineapple crown extract as corrosion inhibitor of aluminum in 1M H2SO4 acidic medium was tested using weight loss and potentiodynamic methods, at varied inhibitor concentration. Through the data from the weight loss method there was calculated the corrosion rate and pineapple crown extract’s inhibition on aluminum corrosion in acidic medium, at varied inhibitor concentration. Also, with the data obtained from the potentiodynamic method, the polarization curves and Tafel tangents were constructed, while calculating the corrosion rate and inhibition efficiency of pineapple crown extract. Experimental measurements showed that pineapple crown extract acts as a mixed inhibitor and the inhibition efficiency increases with increasing the extract concentration.
