The separation of lactobionic acid (LBA), a product of a biotechnological process catalyzed by the enzymes glucose-fructose oxidoreductase and glucono-δ-lactonase of the bacteria Zymomonas mobilis, was studied using ion selective membranes in electrodialysis (ED). The recovery of LBA, present in a solution with a concentration of 20 g L –1 , was 38.7% in 250 min of testing for an electrical...
Electrodialysis (ED) was used to purify ionic liquids systems. It was expected that impurity ions could be separated from the ionic liquid system. Competitive transport behavior was extensively investigated between ionic liquids and impurity ions. [BMIM][CH 3 COO] and NaCl were used as a model ionic liquid and impurity ions, respectively. Two types of membranes including homogeneous and heterogenous...
