How hydroxyl ions interact with bacteria
Web1 nov. 2001 · Abstract. Surface hydroxyl groups on metal oxides are sites for adsorption of cations or anions from water, which in turn release protons or hydroxide ions to solution resulting in ion-exchange reactions. It is important to know the mechanism of the formation of surface hydroxyl groups to understand the ion-exchange capacities and properties of ...
