摘要

由于科学技术领域对绿色化学的需求日益增加，对绿色缓蚀剂的开发提出了很高的要求。植物提取物作为缓蚀剂的应用已引起广泛关注。本文研究了菠萝冠提取物在1M h2so4和1M HCl中对钢39的缓蚀作用。采用减重法进行缓蚀剂效率试验。缓蚀剂的缓蚀效率随缓蚀剂浓度的增加而增加。在浓度为3g/L时，对腐蚀性介质中39号钢的防护效果为82.88%。结果表明，凤梨冠提取物对钢39和环境都是很好的选择。

Pineapple Crown Extract As Green Inhibitor for Steel 39 in Acidic Media

- The development of green corrosion inhibitors are highly demanded because of the increasing demand of green chemistry in the area of science and technology. Use of plant extracts as corrosion inhibitors has attracted significantly attention. The present study investigates corrosion inhibition of pineapple crown extract for steel 39 in 1M H₂SO 4 and 1M HCl. The weight loss method is used for inhibitor efficiency testing. The inhibition efficiency of inhibitor increases with the increases of concentration of inhibitor. Use of this inhibitor in concentration 3g/L present protection efficiency 82.88 % for steel 39 in aggressive media. The results present that pineapple crown extract is a good choice for steel 39 and environment, too.
