摘要
用失重法研究了在盐酸介质中 ,稀土镧 ( )离子对铝腐蚀速度的影响以及L a3+和非离子表面活性剂聚乙二醇辛基苯基醚 ( OP)对铝的缓蚀协合效应 ,发现L a3+对铝有较强的增蚀作用 ,而 La3+和
The effect of rare earth lanthanium( ) ion on corrosion rate of aluminium and synergism of corrosion inhibition between La3+and nonionic surfactant polyethlene glycol mono- ( p) octyl phenyl ether( OP) for aluminium in hydrochloric acid medium have been in- vestigated by weight loss method.It is found that La3+ion accelerates corrosion rate of alu- minium.The inhibition synergism by adding both L a3+and OP in hydrochloric acid medium is dramatically exhibited.
