초록

공기가 제거된 0.5 M HCl 과 0.5 M NaCl 용액에서 일어나는 알루미늄의 부식에 대하여 알라닌(Ala), 히스티딘(His) 과 메티오닌(Met)의 부식억제 효과를 조사하였다. HCl에 용해된 Ala, His, Met의 경우 모두 환원반응 속도가 감소되어 부식이 억제 되었으며, 부식억제 효율은 Met$10^{-4\;}M$ 보다 묽은 용액에서 Langmuir 흡착 등온식이 적용되었으나 $10^{-4\;}M$ 보다 진한 용액에서는 흡착된 분자 사이의 상호작용에 의하여 Temkin의 대수함수 등온식이 적용되었다.

Inhibition effects of alanine (Ala), histidine (His), methionine (Met) on the corrosion of aluminum were investigated in deaerated 0.5 M HCl and NaCl solution. In HCl solution the inhibition efficiency for the aluminum corrosion depended on the cathodic inhibition, and the inhibition efficiency was increased in the order of Met$10^{-4\;}M$ the adsorption process can be explained by Langmuir isotherm, however, in the case of higher concentration by Temkin logarithmic isotherm due to the interaction between the adsorbed molecules.
