摘要
测定了不同浓度和流速下的盐水和氨基酸盐溶液的极限电流密度,分析了浓度、流速、氨基酸含量等因素对电渗析极限电流密度的影响,提出了描述电渗析特性的数学模型。初步研究了应用电渗析对氨基酸盐溶液进行处理时,流速和电压对脱盐率和氨基酸回收率的影响,用较低的流速在接近极限电流密度的条件下操作能达到最好的分离效果。
The limiting current density of salt solution with and without amino acid of different concentrations under different flow rates were measured. The influences of salt concentration, flow rate and amino acid concentration on the limiting current density of electrodialysis were studied. A model was proposed to describe the electrodialysis. The influences of flow rate and electrical voltage on the desalting ratio and the recovery of amino acid were examined during the electrodialysis of mixed solution of salt and amino acid. Working at a lower velocity but a current density close to the limiting current density good separation result was obtained.
