花开的季节33

[求助] 各位同仁们,求翻译,急需,谢谢啦!!!!! 已有1人参与

氨基酸具有绿色、经济、高效等优点,成为缓蚀剂研究的重要方向。本文采用电化学方法研究了丙氨酸、丙氨酸与碘化钾复配对碳钢在硫酸介质中缓蚀性能的影响。实验结果表明:在10%的硫酸体系中,丙氨酸对碳钢的缓蚀性能随着丙氨酸浓度增大而增强,单独使用丙氨酸作为缓蚀剂,缓蚀效果不明显。经过丙氨酸与碘化钾复配后,缓蚀效果显著增强,当丙氨酸浓度为300mg/L,碘化钾浓度为250mg/L时,缓蚀效率达到92.82%,说明二者具有很好的协同作用。通过对缓蚀剂的缓蚀作用和El-Awady动力学模型的研究,得出该缓蚀剂为混合型缓蚀剂,通过物理吸附和化学吸附,为多分子层吸附。

Amino acid has advantages such as green, economic, high efficiency, and it is becoming  an important direction of corrosion inhibitor’s researchment. This paper used electrochemical method to study Alanine and Alanine compound with potassium iodide’s corrosion inhibition to carbon steel in sulfuric acid. The experiment result shows that: in the system of 10% sulfuric, Alanine’s corrosion inhibition to carbon steel is enhanced along with the increase of Alanine’s concentration, and use Alanine alone as corrosion inhibitor the corrosion inhibition effect is not evident. After compound Alanine with potassium iodide, corrosion inhibition effect is enhanced, and when Alanine’s concentration is 300mg/L, potassium iodide’s concentration is 250mg/L, the corrosion inhibition efficiency reached 92.82%, which illustrated this two have great synergistic effect. After research on corrosion inhibitor’s effect and El-Awady dynamical model, the conclusion has come out that this corrosion inhibitor is mixed corrosion inhibitor, through physical and chemical absorption, is multiple molecular layer absorption.

300PPM,的缓蚀剂加250ppm的碘化钾,这个成本真够高
来吧,来吧
