S. Resbeut et al., Electromembrane processes for waste stream treatment: electrodialysis applied to the demineralization of phenylalanine solutions, DESALINATN, 120(3), 1998, pp. 235-245
The recovery of DL-phenylalanine with the simultaneous removal of salts was
obtained at laboratory scale by conventional electrodialysis using CDS and
ADP commercial ion-exchange membranes (Solvay). The demineralization ratio
(95%) and the amino acid recovery (85%) did not depend on the applied curr
ent density. A batch-mode was carried out at 60 mA.cm(-2) without any irrev
ersible sorption effect of the amino acid within the ion-exchange membranes
.
