Abstract

Corrosion inhibition effects of water-soluble peripheral substituted cobalt, copper and zinc metallophthalocyanines (CoPc (1), CuPc (2) and ZnPc (3)) on the copper metal in 0.1 N HCl were investigated by using gravimetric, electrochemical, SEM-EDS analysis and quantum chemical calculations. On the electrochemical investigations and gravimetric analysis the highest inhibitor efficiency was obtained with CoPc (1) at 1 × 10–2 mol/L concentration. SEM-EDS results indicated parallel results and oxygen atom content increased in the order of ZnPc (3), CuPc (2) and CoPc (1). According to the quantum chemical calculations, following corrosion inhibition efficiency ranking was obtained: CoPc (1) > CuPc (2) > ZnPc (3).

水溶性外围酞菁作为铜在0.1 N HCl中的腐蚀抑制剂:重量分析,电化学分析,SEM-EDS分析和量子化学计算

摘要

采用重量法,电化学法,SEM-EDS法研究了水溶性外围取代的钴,铜和锌金属酞菁(CoPc (1),CuPc (2)和ZnPc (3))在0.1 N HCl中对铜金属的腐蚀抑制作用。分析和量子化学计算。在电化学研究和重量分析中,使用CoPc (1)在1×10 –2 mol / L的浓度下可获得最高的抑制剂效率。SEM-EDS结果表明平行结果且氧原子含量按ZnPc (3),CuPc (2)和CoPc (1)的顺序增加。根据量子化学计算,获得以下腐蚀抑制效率等级:CoPc (1) > CuPc (2) > ZnPc (3)
