Effects of Calcium Salts and Amino Acids in Simulated Feed of Isoelectric Supernatant on Membrane Fouling during Bipolar Membrane Electrodialysis
钙盐和氨基酸对味精等电母液模拟料双极膜电渗析过程膜污染的影响

The individual role of Ca2+ salts and amino acids on membrane fouling from a bipolar membrane electrodialysis(BMED) of simulated monosodium glutamate isoelectric supernatant was studied with a constant voltage batch operation mode.Experimental results showed that some amino acids including Glu,Ala,Gly,Thr and Lys were detected in a content order of Glu>Ala>Gly>Thr>Lys in the base cell,which was proportional to their respective content in salt solution.The calcium existing in feed liquor was responsible main...
