- •
Asymmetric CDI system tested with different operating parameters and salt solutions.
- •
Two different mechanisms for ion adsorption appeared to occur.
- •
CDI system performance was shown to be anion dependent.
- •
Sulfate interactions were shown to decrease ion desorption from the electrodes.
- •
Anode oxidation led to electrosorption capacity loses and solution acidification.
