文摘
- •
Electrosorption selectivity in a competitive multi-ionic solution was studied.
- •
Monovalent ions with a low hydration ratio exhibit high selectivity.
- •
Divalent ions demonstrate higher selectivity than monovalent ions.
- •
The adsorbed ion is easily substituted by ions with lower hydration ratios.
