摘要：
The process of electrodialysis of 0.05 M hydrochloric acid solutions containing 0.2% pectins with different molecular mass was studied using ion-exchange membranes. It is found that occurrence of the process at the current density of 5 mA/cm2 allows achieving the solution demineralization degree of 87–90% and acid regeneration degree of 86–92% at current efficiency of 63–77%. Higher process indicators are observed in the case of electrodialysis of solutions containing pectin of a lower molecular mass.
