摘要
用失重法研究了非离子表面活性剂Tween 80在三种无机酸介质 (HCl、H2 SO4 、H3PO4 )中对钢的缓蚀作用 .实验表明 ,非离子表面活性剂Tween 80在三种无机酸介质中对钢有较好的缓蚀作用 ,应用Langmuir吸附方程讨论了产生缓腐蚀作用的原因 ,分析比较了Tween
Non-surfactant Tween 80 was examined as corrosion inhibitor for steel in three inorganic acid solutions (HCl, H 2SO 4, H 3PO 4) by weight-loss method. The remarkable corrosion inhibition of Tween 80 for steel was found in three inorganic acid solutions (HCl, H 2SO 4, H 3PO 4) for mild steel. The reason of producing inhibition effect was discussed in the light of Langmuir adsorption theory. The percentage inhibition efficiency (P) of Tween 80 is also compared between the three acid solutions.
