摘要

应用失重法、电化学方法、扫描电镜等研究十二烷基三甲基溴化铵(DTAB)、咳特灵(KTL)复合添加剂抑制锌在KOH(3mol/L)溶液的缓蚀作用.结果表明:与单一添加剂相比,DTAB-KTL复合添加剂缓蚀效果更好.由于二者的协同效应,使KTL更容易吸附在锌电极DTAB表面,提高缓蚀作用.

Abstract

The electrochemical behaviors of Zn in 3mol/L KOH solution containing several kinds of inhibitors were investigated by weight-loss,electrochemical methods and SEM. The results showed that both the single ad-ditive and the mixed additives can suppress the corrosion of zinc in 3 mol/LKOH solution. And the inhibition ef-feciency of the mixed additives is higher than that of any single additive because of the synergistic effect between KTL and DTAB. The adsorption of DTAB on the surface of zinc has been enhanced in the presence of KTL.
