Abstract

This research article aims to investigate the anti-corrosion performance and heavy metal ion detection using Cholesteryl hemisuccinate (CHEMS) mainly an amphiphilic molecule. For corrosion inhibition studies, electrochemical methods were utilized that showed inhibition efficiencies, maximum of 84.03% in 1 M HCl and 85.43% in 1 M H₂SO₄ at 80 ppm (EIS studies). A mixed type of inhibition, with a strong cathodic influence in 1 M HCl and a strong anodic influence in 1 M H₂SO₄ media as evaluated by PDP studies. The temperature-dependent measurements indicated that the adsorption of CHEMS on MS exhibited Langmuir adsorption behaviour in both acidic media. Surface morphology studies provided supporting evidence for the proposed inhibition mechanism. To understand further, the mechanism of inhibition, theoretical studies such as Density Function Theory (DFT) and Monte Carlo simulation (MCS) were conducted. The electrochemical sensing studies using CHEMS-modified glassy carbon electrode (CHEMS-GCE) provides ultra-high sensitivity, enabling the detection of Hg²⁺ions at low concentrations.

半琥珀酸胆甾醇的缓蚀研究与重金属离子检测相结合

本文主要研究了两亲性分子半琥珀酸胆甾醇（CHEMS）的防腐性能和重金属离子检测。在缓蚀研究中，电化学方法显示了缓蚀效率，在1 M HCl和1 M H2SO4 （80 ppm）中，缓蚀效率最高为84.03%和85.43% （EIS研究）。混合类型的抑制，在1 M HCl中有很强的阴极影响，在1 M H2SO4介质中有很强的阳极影响，经PDP研究评估。温度依赖性测量表明，化学物质在质谱上的吸附在两种酸性介质中均表现出Langmuir吸附行为。表面形貌研究为提出的抑制机制提供了支持证据。为了进一步了解抑制机制，进行了密度函数理论（DFT）和蒙特卡罗模拟（MCS）等理论研究。化学修饰玻碳电极（chemicals - gce）的电化学传感研究提供了超高灵敏度，可以检测低浓度的Hg2+离子。
