4-氨基安替比林在盐酸溶液中对碳钢的缓蚀行为
Inhibition Behavior of 4-Aminoantipyrine on Carbon Steel in HCl Solution
摘 要
采用失重法、动电位极化曲线、电化学阻抗谱研究了4-氨基安替比林在盐酸介质中对碳钢的缓蚀行为。结果表明, 4-氨基安替比林是一种同时抑制阳极和阴极反应的混合型缓蚀剂, 缓蚀效率随缓蚀剂浓度增加而增大, 4-氨基安替比林在碳钢表面的吸附吉布斯自由能为-30.52 kJ·mol-1, 是一种介于物理吸附与化学吸附之间的混合型自发吸附, 符合Langmuir等温吸附式。

Abstract
The inhibition behavior of 4-Aminoantipyrine on carbon steel in HCl solution was studied by weight loss testing, potentiodynamic polarization curvers and electrochemical impedance spectroscopy. The results show that the inhibition efficiency increased with the increase of 4-Aminoantipyrine concentration. 4-Aminoantipyrine is a mix-type inhibitor which can inhibit the reaction of anode and cathode, and the standard free Gibbs energy of adsorption is -30.52 kJ·mol-1, which indicates that 4-Aminoantipyrine can adhere on carbon steel surface with a kind of spontaneous adsorption model between physical adsorption and chemical adsorption, and obeys Langmuir isotherm.
