Abstract
In this work, the possibility and effectiveness of a zinc salt recovery from simulated zinc electroplating wastes by electrodialysis enhanced with citric acid were discussed. It was concluded that zinc recovery exceeded 86%, with current efficiency in the range from 84.9% to 93.7%. Moreover, high iron retention coefficients equal to 92.4% and 94.5% respectively for experiments were observed. Lower value of retention coefficient was determined for copper ions (72.7% and 58%). It was found that electrodialysis enhanced with complex formation can be used for selective zinc recovery from wastewater.
