| 摘 要： | 从麻竹(Dendrocalmus latifcorus Munro)竹叶中提取出的固体物质,可以作为一种环境友好型植物缓蚀剂。用失重法研究了麻竹竹叶提取物在1.0 mol/L HCl1、.0 mol/L H2SO4和1.0 mol/L H3PO4三种酸性溶液中对冷轧钢的缓蚀作用。结果表明:麻竹竹叶提取物对冷轧钢的缓蚀率随缓蚀剂浓度的增加而增大,当其浓度为200 mg/L时,三种酸溶液中的缓蚀效率可分别达到92.3%(HCl)、88.9%(H2SO4)、75.8%(H3PO4)。且在钢表面的吸附符合校正的Langmuir吸附等温式。并根据试验结果探讨了缓蚀机理。

| Abstract: | Solid extractive from dendrocalmus latifcorus Munro leaves was investigated as an excellent environmental-friendly plant inhibitor.The inhibition effect of the plant extractive on cold rolled steel(CRS) in three mineral acids(1.0 mol/L HCl,1.0 mol/L H2SO4 and 1.0 mol/L H3PO4) was studied by weight loss method.The results showed that the inhibition efficiency of the extractive in three mineral acids for CRS was 92.3%(HCl),88.9%(H2SO4),75.8%(H3PO4) respectively.The adsorption of the plant inhibitor on the CRS... |
