ISOLUTE® AL-A is a high activity, 50-200 µm particle size range alumina. The surface of the alumina can absorb molecules by interaction with the aluminium metal centre, hydrogen bonding with surface hydroxyl groups, or by ion exchange if the surface carries a charge. 


Acid washing results in a surface with decreased capacity for basic compounds. Compounds are retained by ion exchange with the positively charged surface, or by specific interactions with the metal centre.
