摘要
表面活性剂是一种表面活性剂。表面活性剂的分子结构中既有亲水（吸水）部分，也有疏水（拒水）部分，是保护酸性介质中低碳钢的有效抑制剂。在实验室温度下，采用失重法评估了表面活性剂十六烷基吡啶氯化物（CPC）和十二烷基硫酸钠（SDS）对 0.5 M H2SO4 溶液中低碳钢腐蚀保护行为的影响。研究了不同浓度表面活性剂对低碳钢的抑制效率、重量损失、腐蚀速率和表面覆盖面积。结果表明，在 0.5 M H2SO4 溶液中，十六烷基氯化吡啶的抑制效率为 99.86%，高于十二烷基硫酸钠的抑制效率（99.85%）。
Study of Anti-Corrosion Properties of Sodium Dodecyl Sulphate and Cetyl Pyridinium Chloride
Surfactant is a surface-active agent. Surfactants have both hydrophilic (water-attracting) and hydrophobic (water-repelling) portions in their molecular structure, effective inhibitors for the protection of mild steel in an acidic medium, the weight loss methods were used at lab temperature to evaluate the effect of surfactant cetyl pyridinium chloride (CPC) and sodium dodecyl sulfate (SDS) on the corrosion protection behavior of Mild steel in 0.5 M H2SO4 solution. Inhibition efficiency, weight loss, corrosion rate, and surface coverage area of Mild steel in different concentrations of surfactant were studied. The results showed that the Inhibition efficiency of cetyl pyridinium chloride is 99.86%, which is greater than that of sodium dodecyl sulfate (99.85%) in the presence of 0.5 M H2SO4.
