摘要
采用失重法研究了不同温度下不同质量浓度的溴化十六烷基吡啶在3%的氢氟酸介质中对碳钢的缓蚀作用。结果表明,溴化十六烷基吡啶在3%的氢氟酸介质中对碳钢的腐蚀具有良好的抑制作用。溴化十六烷基吡啶在碳钢片表面的吸附规律基本服从Langmuir等温式。采用Sekine方法处理实验数据,获得了吸附系数、焓变、熵变、自由能变等相关热力学参数。
The corrosion inhibition of cetylpyridinium bromide on carbon steel content in 3% hydrochloric acid was studied with different temperatures and different mass concentration of cetylpyridinium bromide by weight-loss method.It is shown by the result that Cetylpyridinium Bromide has efficiently inhibited the corrosion of Carbon Steel in 3% acid solution,the adsorption rule of Cetylpyridinium Bromide on the surface of Carbon Steel obeyed Langmuir isotherm..Using Sekine method for processing experimental data,obtained by adsorption coefficient,enthalpy,entropy,free energy change and related thermodynamic parameters.
