本文采用分光光度法研究低碳钢在硫酸溶液中的腐蚀及TX—100对其腐蚀的影响。在30℃至45℃范围内,TX—100随浓度的增加表现出明显的缓蚀作用,且温度升高缓蚀作用增强。根据实验结果,对缓蚀机理和腐蚀动力学进行了研究。结果表明,TX—100的加入并不改变腐蚀反应的机理,缓蚀作用的重要原因是TX—100在低碳钢表面上发生了吸附,这种吸附符合Langmuir吸附方程式。
In this paper, the use of spectrophotometry corrosion of mild steel in sulfuric acid solution and TX-100 on its corrosion. In the range of 30 ℃ to 45 ℃, TX-100 shows a significant inhibition effect with the increase of concentration, and the corrosion inhibition with temperature increase is enhanced. According to the experimental results, the corrosion inhibition mechanism and corrosion kinetics were studied. The results show that the addition of TX-100 does not change the mechanism of corrosion reaction. The main reason for corrosion inhibition is the adsorption of TX-100 on the surface of mild steel, which accords with the Langmuir adsorption equation.
