摘要
采用失质量法研究了硫脲在氢氟酸中对碳钢的吸附及缓蚀作用,并应用吸附理论Sekine方法对实验数据进行处理.结果表明,硫脲对氢氟酸体系中碳钢的腐蚀有良好的抑制作用,硫脲在碳钢片表面产生了吸附,且低浓度下吸附基本符合Langmuir等温式.
The adsorption and corrosion inhibition of thiourea on carbon steel in hydrochloric acid has been investigated by weight-loss method. The experimental data have been treated with adsorption theory and sekine method. The result showed that thiourea has efficiently inhibited the corrosion of iron in hydrofluoric acid solution, the adsorption rule of thiourea on the surface of iron obeyed Lanzmuir isotherm.
