Web13 apr. 2024 · Due to the bulkiness of the ionic liquid and although the “on-top” configuration is energetically favoured for less basic anions [21,38,39], ions arrange to reduce repulsion where the anions and cations can alternate in a “side to side” fashion to avoid the repulsion of anions next to each other . Webionic effects indicates that these separations occur by anion repulsion, not by cation exchange. Cation exchange, previously held reponsible for these separations, is inoperative since nucleotides at acid pH values bear net negative charges, as do the fixed anions of the resin. The separations
