采用电化学方法研究了柚子提取液+Na_2MoO_4复配对碳钢在3.5%NaCl中的缓蚀协同效应,找到最佳复配比。结果表明:柚子皮提取液+Na_2MoO_4属于混合抑制性缓蚀剂,在0.02 g/m L柚子皮提取液和10g/LNa_2MoO_4复配时缓蚀效果最好,对碳钢的缓蚀效率可达到92%,满足了Langmuir等温吸附方程,且反应自发进行。
The synergistic effect of citric acid extract + Na_2MoO_4 compound on corrosion inhibition of carbon steel in 3.5% NaCl was studied by electrochemical method, and the best compounding ratio was found. The results showed that the extract of grapefruit peel + Na 2 MoO 4 belongs to mixed inhibitor, and the best corrosion inhibition effect is obtained when the mixture of grapefruit peel (0.02 g / m L) and 10 g / L Na 2 MoO 4 is compounded, and the corrosion inhibition efficiency of carbon steel can reach 92 %, Satisfy the Langmuir Isothermal adsorption equation, and the reaction spontaneously.
