| 摘 要： | 本文通过失重法研究盐酸溶液中,单一油酸钠以及添加硫酸高铈对铝的缓蚀效果,结果表明油酸钠对铝在盐酸溶液中有一定的缓蚀效果,添加硫酸高铈后,能产生明显的协同缓蚀作用。油酸钠在铝表面吸附不符合兰缪尔吸附,添加硫酸高铈后遵守兰缪尔吸附。

| Abstract: | The inhibitive effect of sodium oleate without and with ceric sulfate for aluminium in hydrochloric acid solution was studied by weight-loss method.The results showed that sodium oleate was a good inhibitor for aluminum in 1molL-1 HCl,but the inhibition efficiency is rapidly reduced as the increase of concentration of hydrochloric acid.The synergistic effects of sodium oleate and Ce(SO4)2 on the corrosion of aluminum in 2molL-1 HCl were also studied.By fitting the experimental data,it was found that the res... |
