| 摘 要： | 用失重法研究了在盐酸介质中阴离子表面活性剂十二烷基磺酸钠（ＤＳＡＳＳ），十二烷基苯磺酸钠（ＤＢＳＡＳ）以及十二烷基硫酸钠（ＳＤＳ）对铝的缓蚀作用；提出这种缓蚀作用与表面吸附有关且符合Ｌａｎｇｍｕｉｒ方程，从而计算出吸附热，吸附熵，吸附自由能等热力学参数，讨论了吸附方式及缓蚀作用之间的关系。

| Abstract: | he corrosion inhibition of several anion surfactants such as dodecyl sulphonic acid sodiumsalt(DSASS),dodecyi benzene sulfonic acid sodiumsait(DBSAS)and sodium dodecyl sulfate(SDS)for alu-minium in hydrochloric acid rnedium has been investigated by weight loss method.The idea is brought outthat the corrosion inhibition is related to surface adsorption,and it obeys langmuir equation.Thus,suchthermodynamic parameters as adsorption heat,adsorption entropy and adsorption free energy are calculated.Moreover,the relation between absorption pattern and corrosin inhibition is also discussed. |
