-
Activated alumina has many capillary channels and a large surface area. It can be used as an adsorbent, desiccant, and catalyst. It also determines the affinity based on the polarity strength of the adsorbed substances. It has strong affinity for water, oxides, acetic acid, alkalis, etc. It is a micro-water deep desiccant and an adsorbent for polar molecules.
