研究了不同电位和浓度下活性炭电极的电吸附性能。结果表明，电吸附容量和速率随偏压和溶液浓度的增加而增加。发现这种趋势与静电力的增加和电解质电阻的减小相关。电吸附等温线的研究表明，实验数据可以很好地用朗缪尔等温线表示。动力学分析表明，NaCl在AC电极上的电吸附符合准一级动力学模型。(c)2010年爱思唯尔。All rights reserved.
The electrosorption performance of activated carbon (AC) electrodes with various potentials and concentrations was studied. It was found that electrosorption capacity and rate increased with the increasing of the bias potentials and solution concentrations. Such trend was found to be correlated to the increase of the electrostatic force and the decrease of the electrolyte resistance. The investigation of the electrosorption isotherm showed that the experimental data can be well represented by Langmuir isotherm. And the kinetics analysis indicated that the electrosorption of NaCl onto AC electrodes followed pseudo-first-order kinetics model. (c) 2010 Elsevier By. All rights reserved.
