摘要

在油气行业中，碳钢管道的腐蚀给操作和环境带来了挑战，需要更安全的替代品来替代有毒的缓蚀剂。本研究利用电化学和表面分析技术对硅q -22 （SQ22）作为绿色缓蚀剂进行了评价。在125 ppm浓度下，SQ22对斑马鱼胚胎的EIS和PDP的抑制率分别为88.24%和83.31%,LC50 = 22.36 mg/L，毒性最小。低于2 mg/L （NOEC）时，SQ22无明显毒性，但对心脏有轻微影响。凭借高效、低环境影响，SQ22在工业腐蚀控制中成为一种有前途的、可持续的替代方案。

Silicone quaterium-22 surfactant as an eco-friendly carbon steel anticorrosive: Assessment of corrosion inhibition properties and ecotoxicity in zebrafish embryos

Corrosion of carbon steel pipelines in the oil and gas industry presents operational and environmental challenges, requiring safer alternatives to toxic corrosion inhibitors. This study evaluates Silicon-Q-22 (SQ22) as a green corrosion inhibitor using electrochemical and surface analysis techniques. SQ22 achieved 88.24 % (EIS) and 83.31 % (PDP) inhibition at 125 ppm and exhibited minimal toxicity in zebrafish embryos (LC50 = 22.36 mg/L). Below 2 mg/L (NOEC), SQ22 caused no significant toxicity but induced minor cardiac effects. With high efficacy and low environmental impact, SQ22 emerges as a promising, sustainable alternative for corrosion control in industrial applications.
