电解质溶液对电化学除氯效果的影响

Influence of the electrochemical salt releasing efficiency on different electrolyte solution

电解质溶液是电化学除盐过程中必备的物质条件之一,着重研究不同电解质对电化学除盐效果的影响。试验结果表明:在0.1mol/LNa3BO3溶液中和饱和Ca(OH)2溶液的除盐效果相差不大,且除盐效率比较好;无论在哪种电解质中进行电化学除盐,混凝土中的Cl-含量以钢筋为中心由内及外呈梯度递增分布;而K+、Na+等阳离子含量则是由内及外呈梯度递减的规律,且内层含量远远高于外层含量。

This project discusses the salt releasing efficiency under different electrolyte solution.Result shows：the salt releasing efficiency is similar and well in saturated Ca（OH）2 solution and 0.1 mol/L Na3BO3 solution;after the electrochemical salt releasing in any electrolyte solution,the Cl-in the concrete increase from inside to outside in the distribution of ladder,centering the steel,however the K＋ and Na＋ decrease from the inside to the outside in the distribution of the ladder.
