Abstract

The use of Gaviscon expired drug as the corrosion inhibitor on the carbon steel was studied in the 0.1 M HCl solution at 303, 313, 323 and 333 K by electrochemical method. Gaviscon was demonstrated to be an effective inhibitor for carbon steel, the efficiency reached 80.7% at concentration of inhibitor 24 mL/L at 303 K, 91.973% for 48 mL/L at 313 K, 89.42% for 48 mL/L at 323 K and 97.81% for 24 mL/L at 333 K. The polarization resistance of Gaviscon was revealed, and the highest value was 121.758 for 24 mL/L at 333 K. The surface morphology of the carbon steel was analyzed using scanning electron microscopy (SEM) to show the film randomly distributed throughout the entire carbon steel surface. The antibacterial activity of the inhibitor was also tested by agar well diffusion which exhibit that no inhibition zone was observed, indicating that the Gaviscon drug was reactivity against E. coli. and S. aureus bacterial. Fourier-transform infrared spectroscopy (FTIR) for the Gaviscon drug confirmed the inhibitory role of inhibition efficiency.

用加夫iscon过期药物作为酸性溶液中的缓蚀剂减少碳钢的腐蚀
用电化学方法研究了在0.1 M HCl溶液中,在303、313、323和333 K下,加夫斯康过期药物作为碳钢的缓蚀剂的作用。Gaviscon是一种有效的碳钢缓蚀剂,在3030k下,24 mL/L缓蚀剂的效率为80.7%,在313k下,48 mL/L的效率为91.973%,在323k下,48 mL/L的效率为89.42%,在3333k下,24 mL/L的效率为97.81%。结果显示,在333 K下,24 mL/L时,Gaviscon的极化电阻最高为121.758。利用扫描电镜(SEM)分析了碳钢的表面形貌,发现薄膜随机分布在整个碳钢表面。通过琼脂孔扩散法测试了该抑制剂的抗菌活性,结果显示没有观察到抑制区,表明Gaviscon药物对大肠杆菌具有反应性。金黄色葡萄球菌。傅里叶变换红外光谱(FTIR)对加夫iscon药物的抑制作用进行了验证。

期刊介绍: Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
