摘要

为了探明菠菜提取物与KI 复配在0.5 mol/L H2SO4溶液中对Q235 钢的协同缓蚀作用,利用失重法、电化学阻抗谱(EIS)、动电位极化曲线、扫描电镜(SEM)及能谱分析(EDS)探讨了0.5 mol/L H2SO4介质中菠菜提取物叶绿素(CHL)与KI 对Q235 钢材料的缓蚀协同作用及机理。结果表明:在0.5 mol/L H2SO4溶液体系中,CHL(100 mg/L)与KI(50~200 mg/L)复配时都表现出较好的缓蚀作用,缓蚀率都在90%以上,且当CHL 与KI 分别以100 mg/L 的浓度复配时,协同作用最好,缓蚀率高达98.04%。CHL 与KI 复配属于抑制阴极为主的混合型缓蚀剂。CHL 及其与KI 的复配物的缓蚀行为符合Langmuir 等温吸附方程,为自发吸附过程,Q235 钢表面形成了致密的保护膜。在0.5 mol/L H2SO4溶液体系中,CHL 分子通过物理和化学吸附共同作用,吸附在Q235 钢表面,阻止腐蚀反应发生。KI 加入后,协助CHL 分子吸附在Q235 钢表面,提高了CHL 分子的吸附率,表现为在降低腐蚀速率的同时,减少了CHL 分子和KI 的用量,增强了二者的协同效应进而提高了缓蚀率。

Abstract

In order to explore the synergistic corrosion inhibition effect of spinach extract and KI on Q235 steel in 0.5 mol/L H2SO4 solution,the synergistic corrosion inhibition effect and mechanism of spinach extract chlorophyll (CHL) and KI on Q235 steel in 0.5 mol/L H2SO4 solution were studied by means of weight loss method,electrochemical impedance spectroscopy (EIS),potentiodynamic polarization curve,scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS).Results showed that when CHL (100 mg/L) and KI (50~200 mg/L) were combined in 0.5 mol/L H2SO4 solution,the obtained compound always showed good corrosion inhibition with a corrosion inhibition rate above 90%.And when both CHL and KI were mixed with a concentration of 100 mg/L,the synergistic effect was the best,with a corrosion inhibition rate up to 98.04%.The compound of CHL and KI was a kind of mixed corrosion inhibitor that mainly inhibited the cathode.The corrosion inhibition behavior of CHL and its complex with KI conformed to Langmuir isothermal adsorption equation,which was a spontaneous adsorption process and formed a dense protective film on the surface of Q235 steel.In 0.5 mol/L H2SO4 solution,CHL molecules were adsorbed on the surface of Q235 steel through physical and chemical adsorption to prevent corrosion reaction.The addition of KI could assist CHL molecules to adsorb on the surface of Q235 steel,improving the adsorption rate of CHL molecules.In this way,the corrosion rate as well as the amount of CHL and KI required for the inhibition were both reduced.Therefore,the synergistic effect of CHL and KI was enhanced and the inhibition efficiency was improved.
