摘要
摘要:采用失重法研究了稻壳提取物在1 M H2SO4溶液中降低低碳钢腐蚀速率的能力。XRD分析了稻壳提取物的二氧化硅结构。在不同浸泡时间(2、4、6和8 h)下，以不同浓度(0、10、15、20和25 ppm)加入稻壳提取物作为缓蚀剂，结果表明稻壳提取物对低碳钢具有良好的缓蚀剂效果。稻壳提取物在1 M H2SO4溶液中的缓蚀率可达4.77 mmpy，缓蚀率超过90。x射线衍射(XRD)分析表明，稻壳提取物中存在的二氧化硅结构是无定形的，从而使其更加环保。
Rice Husk Extracts Ability to Reduce the Corrosion Rate of Mild Steel
Abstract—Rice husk extracts ability to reduce the corrosion rate of mild steel in 1 M H2SO4 solution was studied using weight loss technique. XRD analyzed silica structure of rice husk extracts. The Inhibitor was added in various concentrations (0, 10, 15, 20 and 25 ppm) at different immersion times (2, 4 , 6 and 8 h). The results obtained indicate that rice husk extract acts as a good inhibitor for mild steel. Rice husk extract was able to reduce corrosion rate up to 4.77 mmpy with inhibition efficiency exceeded 90 in 1 M H2SO4 solution. X-ray Diffraction (XRD) analysis shows the silica structure present in rice husk extracts is amorphous, thus makes it more environmentally friendly.
